Identification and analysis of JHBP/TO family genes and their roles in the reproductive fitness cost of resistance in Frankliniella occidentalis (Pergande)

The juvenile hormone binding protein (JHBP) and takeout (TO) genes, mediated by the juvenile hormone (JH), play a crucial role in regulating the reproductive physiology of insects. Our previous study revealed that spinosad-resistant Frankliniella occidentalis (NIL-R) exhibited reduced fecundity and significant changes in JHBP/TO family gene expression. We hypothesized that these genes were involved in regulating the fitness costs associated with resistance. In this study, 45 JHBP/TO genes were identified in F. occidentalis, among which FoTO2 and FoTO10 were duplicates. Additionally, eight genes exhibited significant down-regulation in the NIL-R population. Two genes (FoTO6 and FoTO24) that exhibited the most significant differential expression between the spinosad-susceptible (Ivf03) and NIL-R populations were selected to investigate their roles in resistance fitness using RNA interference (RNAi). Following interference with FoTO6, FoTO24, and their combination, the expression levels of vitellogenin (Vg) were downregulated by 3%–30%, 13%–28%, and 14%–32% from the 2nd day to the 5th day, respectively; Krüppel-homolog 1 (Kr-h1) expression was down-regulated by 3%–65%, 11%–34%, and 11%–39% from the 2nd day to the 5th day, respectively; ovariole length was shortened by approximately 18%, 21%, and 24%, respectively; and the average number of eggs decreased from 407 to 260, 148, and 106, respectively. Additionally, a JH supplementation experiment on the NIL-R population revealed that the expression levels of both FoTO6, FoTO24, Vg and Kr-h1 were significantly upregulated compared with those observed in the Ivf03 population, resulting in increased fecundity. These results suggest that FoTO6 and FoTO24 are involved in JH-mediated regulation of the reproductive fitness cost of resistance to spinosad. Further, FoTO6 and FoTO24 can be considered potential target genes for applying RNAi technology in the scientific management of F. occidentalis.

The Effects of Oral Progestagen Administration on the Fertility of Synchronized Goats During the Breeding Season

The objective of this study was to assess the impact of oral progesterone (altrenogest) administered after mating on fertility in goats synchronized during the breeding season. A total of 47 Hair goats were included in the study. A progesterone-impregnated intravaginal sponges were administered for 12 days. On day 10 of intravaginal sponge administration, 480 IU pregnant mare's serum gonadotropin (PMSG) and 0.075 mg cloprostenol were injected intramuscularly to the goats. Animals were exposed to bucks for 12 hours after detection of estrus by the foraging buck. The goats were randomly assigned to two distinct groups: Group 1 (G1, n=23) and Group 2 (G2, n=24). G1 goats were orally administrated 4.4 mg of altrenogest per day for 30 days after mating. G2 goats served as controls. Pregnancy examinations were performed by transrectal ultrasonography on the 30th and 42nd days after mating. Blood samples were taken from one day after mating to 30 days (3-day intervals). Statistical analysis comparing G1 and G2 revealed no significant differences between the groups regarding progesterone concentrations, conception rate, pregnancy rate, lambing rate, multiple birth rate, fecundity, and litter size (p>0.05). In conclusion, this study revealed that oral progesterone use had no impact on fertility parameters. Moreover, further research is warranted to explore the efficacy of various oral progesterone analogs.

Effect of ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation on gastrointestinal reactions of malignant tumor patients undergoing chemotherapy.

To observe the efficacy and safety of ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation in the prevention and treatment of chemotherapy-induced nausea and vomiting (CINV) in patients with malignant tumors. Patients with malignant tumors and suffering from chemotherapy were randomly divided into control group (35 cases, 4 cases dropped off) and observation group (35 cases, 2 cases dropped off). The patients of the control group were treated by orally taking ondansetron hydrochloride tablets 8 mg/time, 3 times a day for 3 d, and those of the observation group treated by ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation of Zusanli(ST36), Neiguan(PC6), Tianshu(ST25), Zhongwan(CV12) and Guanyuan(CV4) once a day for a total of 3 d, based on the treatment of the control group. The patients' gastrointestinal reaction degree after the 1st , 2nd and the 3rd day of treatment were recorded. The Karnofsky performance status (KPS) score (0-100 points) was used for assessing the patients' quality of life. The TCM syndrome score (4 grades：no, mild, medium and severe, i.e. 0, 2, 4 and 6 points) was given according to the patients' severity of symptoms of spleen (stomach) qi deficiency (nausea and vomiting, abdominal distension after eating, belching, loss of appetite, weakness and laziness to speak, fatigue, and loose stool). The safety of the treatment was assessed by examining the patients' blood routine, liver function and kidney function, and the adverse reactions including blisters, allergies, burns and fainting during acupuncture treatment. After the 2nd and 3rd day of treatment, the patients conditions of vomiting and nausea in the observation group were significantly better than those of the control group (P<0.05). The TCM syndrome score and KPS score were significantly decreased in comparison with those of pre-treatment in both groups (P<0.05), and the TCM syndrome score was obviously lower in the observation group than in the control group (P<0.05). No significant differences were found between the two groups in the KPS score after the treatment , and in the levels of white blood cells (WBC), hemoglobin (HGB), platelets (PLT), absolute neutrophil count (ANC), alanine transaminase (ALT), aspartate aminotransferase (AST), creatinine(Cr), and blood urea nitrogen (BUN). The use of ginger-partitioned moxibustion combined with ringheaded thumb-tack needle stimulation is safe for CINV patients, and can effectively relieve nausea and vomiting and alleviate digestive symptoms.

Effects of low-dose acetylsalicylic acid on the inflammatory response to experimental sleep restriction in healthy humans

BackgroundSleep deficiencies, such as manifested in short sleep duration or insomnia symptoms, are known to increase the risk for multiple disease conditions involving immunopathology. Inflammation is hypothesized to be a mechanism through which deficient sleep acts as a risk factor for these conditions. Thus, one potential way to mitigate negative health consequences associated with deficient sleep is to target inflammation. Few interventional sleep studies investigated whether improving sleep affects inflammatory processes, but results suggest that complementary approaches may be necessary to target inflammation associated with sleep deficiencies. We investigated whether targeting inflammation through low-dose acetylsalicylic acid (ASA, i.e., aspirin) is able to blunt the inflammatory response to experimental sleep restriction. Methods46 healthy participants (19F/27M, age range 19–63 years) were studied in a double-blind randomized placebo-controlled crossover trial with three protocols each consisting of a 14-day at-home monitoring phase followed by an 11-day (10-night) in-laboratory stay (sleep restriction/ASA, sleep restriction/placebo, control sleep/placebo). In the sleep restriction/ASA condition, participants took low-dose ASA (81 mg/day) daily in the evening (22:00) during the at-home phase and the subsequent in-laboratory stay. In the sleep restriction/placebo and control sleep/placebo conditions, participants took placebo daily. Each in-laboratory stay started with 2 nights with a sleep opportunity of 8 h/night (23:00–07:00) for adaptation and baseline measurements. Under the two sleep restriction conditions, participants were exposed to 5 nights of sleep restricted to a sleep opportunity of 4 h/night (03:00–07:00) followed by 3 nights of recovery sleep with a sleep opportunity of 8 h/night. Under the control sleep condition, participants had a sleep opportunity of 8 h/night throughout the in-laboratory stay. During each in-laboratory stay, participants had 3 days of intensive monitoring (at baseline, 5th day of sleep restriction/control sleep, and 2nd day of recovery sleep). Variables, including pro-inflammatory immune cell function, C-reactive protein (CRP), and actigraphy-estimated measures of sleep, were analyzed using generalized linear mixed models. ResultsLow-dose ASA administration reduced the interleukin (IL)-6 expression in LPS-stimulated monocytes (p<0.05 for condition*day) and reduced serum CRP levels (p<0.01 for condition) after 5 nights of sleep restriction compared to placebo administration in the sleep restriction condition. Low-dose ASA also reduced the amount of cyclooxygenase (COX)-1/COX-2 double positive cells among LPS-stimulated monocytes after 2 nights of recovery sleep following 5 nights of sleep restriction compared to placebo (p<0.05 for condition). Low-dose ASA further decreased wake after sleep onset (WASO) and increased sleep efficiency (SE) during the first 2 nights of recovery sleep (p<0.001 for condition and condition*day). Baseline comparisons revealed no differences between conditions for all of the investigated variables (p>0.05 for condition). ConclusionThis study shows that inflammatory responses to sleep restriction can be reduced by preemptive administration of low-dose ASA. This finding may open new therapeutic approaches to prevent or control inflammation and its consequences in those experiencing sleep deficiencies. Trial RegistrationClinicalTrials.gov NCT03377543.

Sacubitril/valsartan alleviates sepsis-induced myocardial injury in rats via dual angiotensin receptor-neprilysin inhibition and modulation of inflammasome/caspase 1/IL1β pathway

Sepsis is a life-threatening situation that ultimately affects cardiac function, leading to cardiomyopathy and myocardial injury as a result of uncontrolled response to infection.Till now, there is limited effective treatment to rescue those cases. Thus, novel therapeutic strategies should be identified to achieve better outcomes for septic patients. For the first time, we aimed to evaluate the effect of sacubitril/valsartan (Sac/Val) on sepsis-induced cardiac injury. Wistar male adult albino rats were randomly divided into four groups; Group I received the vehicle; Group II was given the vehicle plus 1 ml saline containing viable Escherichia coli (E. coli) (2.1 × 109 cfu) by intraperitoneal (i.p.) injection on the 1st and 2nd days; Group III received i.p. injection as group II plus oral administration of Sac/Val (30 mg/kg/day) and Nitro- ω-L-arginine (L-NNA) (25 mg/kg/day) for 7 days. Group IV was administered i.p. injection as group II plus oral administration of Sac/Val (30 mg/kg/day) for 7 days. Our data (n = 10) revealed successful induction of sepsis as it showed a significant increase in the measured cardiac enzymes, malondialdehyde (MDA), angiotensin II (Ang II), neprilysin, inflammasome, caspase 1, interleukin (IL)1β, and caspase 3 with cardiac histopathological changes, but there was a significant decrease in the antioxidants and blood pressure (BP). Co-administration of Sac/Val could obviously improve these changes. Interestingly, L-NNA given group showed a decrease in the cardioprotective effect of Sac/Val. Sac/Val could ameliorate sepsis induced cardiac damage via inhibition of Ang II and neprilysin with anti-inflammatory, anti-oxidant and anti-apoptotic properties.

EFFECT OF ORGANIC LEACHATE AND RICE WASHING WATER ON COMPOSTING TIME OF ORGANIC WASTE

Waste is an integral part of human life. The increase in population is one factor that increases the waste generated. The more the population, the more activities are carried out. Organic leachate and rice washing water are environmentally friendly compost activators and are easily obtained from daily activities. Composting is a waste management strategy. Composting is an organic method through the activity of microorganisms to decompose natural materials into materials, including humus. The purpose of this study was to determine the moisture content, temperature, pH, C/N ratio, and macro nutrients during the composting process. The physical parameters of compost from the three activator concentrations showed that the treatment of P3 (with the addition of leachate formulation 20 ml/kg and rice washing water 15 ml/kg) and P2 (with the formulation adding 20 ml/kg leachate and 10 ml rice washing water), the physical compost were brownish black in color, fine textured and smelled of soil on the 22nd day. The P3 treatment has met the quality criteria of compost according to SNI 19-7030-2004, the moisture content (30%), temperature (27°C), pH (6,8), C-Organic (32,9%), Nitrogen (1,42%), Phosphor (0,65%) and Potassium (1,63%). For the C/N ratio, the result of all treatments did not meet the quality criteria of compost according to SNI 19-7030-2004. The C/N ratio of all treatments showed that it is still above the maximum standard that has been set at 20.

Efficacy of adjuvant photobiomodulation therapy in recurrent herpes labialis, a randomized clinical trial study

ObjectiveThis study aimed to determine the effect of Photobiomodulation therapy (PBMT) in the treatment of recurrent herpes labialis (RHL), one of the most common herpes simplex virus type 1 infections. Material and MethodsIn this randomized double blind controlled trial, Twenty-two symptomatic patients with RHL were enrolled. The patients were randomly allocated into one group (5 % acyclovir cream with 940±10 nm wavelength and 4 J/cm2 energy density and 100 mW output power) and another group (5 % Acyclovir 5 times/5 days and sham laser). Lesion size, and pain intensity were considered as the outcome at baseline, 1st 2nd and 3rd days postoperatively. ResultsPain intensity in PBM + Acyclovir group was significantly lower than Acyclovir without PBM group in both two and three days after intervention (p < 0.001). The lesion size in case group was significantly lower on 7 and 10 days (p < 0.05). Patients in the treatment group were significantly more satisfied with their treatment process (p = 0.008). ConclusionPBMT can be used as an adjuvant tool to acyclovir cream, due to higher potential in reducing postoperative pain, lesion size and also patients satisfaction.

Effect of Persistent Salt Stress on the Physiology and Anatomy of Hybrid Walnut (Juglans major × Juglans regia) Seedlings.

Soil salinization has become one of the major problems that threaten the ecological environment. The aim of this study is to explore the mechanism of salt tolerance of hybrid walnuts (Juglans major × Juglans regia) under long-term salt stress through the dynamic changes of growth, physiological and biochemical characteristics, and anatomical structure. Our findings indicate that (1) salt stress inhibited seedling height and ground diameter increase, and (2) with increasing salt concentration, relative water content (RWC) decreased, and proline (Pro) and soluble sugar (SS) content increased. The Pro content reached a maximum of 549.64 μg/g on the 42nd day. The increase in superoxide dismutase (SOD) activity (46.80-117.16%), ascorbate peroxidase (APX) activity, total flavonoid content (TFC), and total phenol content (TPC) under salt stress reduced the accumulation of malondialdehyde (MDA). (3) Increasing salt concentration led to increases and subsequent decreases in the thickness of palisade tissues, spongy tissues, leaves, and leaf vascular bundle diameter. Upper and lower skin thickness, root periderm thickness, root diameter, root cortex thickness, and root vascular bundle diameter showed different patterns of change at varying stress concentrations and durations. Overall, the study concluded that salt stress enhanced the antireactive oxygen system, increased levels of osmotic regulators, and low salt concentrations promoted leaf and root anatomy, but that under long-term exposure to high salt levels, leaf anatomy was severely damaged. For the first time, this study combined the anatomical structure of the vegetative organ of hybrid walnut with physiology and biochemistry, which is of great significance for addressing the challenge of walnut salt stress and expanding the planting area.

Initial orientation and homing performances in the lacertid lizard Podarcis siculus

Homing abilities of lizards after experimental dislocations have been found to be well developed in several species. Following our preliminary findings in Podarcis siculus, the present paper reports a new series of experiments on homing performances and initial orientation behaviour upon release. For this purpose, three series of releases were performed at increasing distances from the home areas in which the lizards were captured (range 85–245 m). In each series, two groups of lizards were released: the route-based visual cues during displacement were denied to one of them (NVIS), but allowed for the other (YVIS). The results of initial orientation showed that both are significantly homeward oriented at all three distances tested. Male and female YVIS and female NVIS are similarly homeward oriented, while the male NVIS are not. All 74 lizards successfully returned to their respective home areas. Eleven lizards homed on the same day they were released, while most of them homed during the 1st day after release (n = 51) and the rest on the 2nd day (n = 12). The different transport treatments did not influence homing success at the different distances tested. These results seem to support the use of a geocentric pilotage strategy to re-enter home from the release spot. Alternatively, the possibility that P. siculus use a sun compass and a mosaic map to find their way home is also discussed.

Clinico-microbiological evaluation of post-cesarean surgical site infections

Objectives: With increasing rates of cesarean section (CS), the incidence of post-operative complications is bound to increase, which includes surgical site infections (SSIs), being one of the common and distressing complication. This study was aimed to evaluate the various determinants of post-CS SSI, their clinical spectrum, prevalent microbiology, and their susceptibility and resistance patterns. Materials and Methods: This was a prospective longitudinal hospital-based study undertaken in Government Medical College and Hospital (GMCH), Chandigarh. Six hundred and eighty-eight patients were included from April, 2021, to September, 2022, and were followed up till 42nd day post-procedure. Results: The incidence of SSI in the study was 3.49%. The risk factors identified were gestational diabetes mellitus (GDM), thrombocytopenia, chorioamnionitis, prolonged labor, multiple per vaginum examinations, prolonged surgery, post-partum hemorrhage, and blood and blood product transfusions. Most patients presented on or after day 8 of surgery with discharge from the wound site being the most common presentation. Staphylococcus aureus emerged as the most prevalent organism and out of five patients having S. aureus, three had methicillin-resistant S. aureus. Linezolid was found to be the most susceptible antibiotic, whereas ciprofloxacin was mostly resistant among the prevalent isolates. Conclusion: Some of these determinants are modifiable such as GDM and thrombocytopenia and if detected and managed early may help in reducing the risk of developing SSI. Linezolid must be used empirically for treatment of SSI until the reporting of culture and sensitivity is done because routine antibiotics used for antibiotic prophylaxis in CS were found to be highly resistant. Periodic analysis of clinical spectrum and culture and sensitivity patterns is imperative for the early diagnosis and appropriate empirical management of SSI.

O-157 The effect of growth hormone on the euploid rate and morphokinetic signature of blastocysts in patients with advanced maternal age : a randomized controlled trial

Abstract Study question Does growth hormone (GH) supplementation during ovarian stimulation affect the euploid rate and morphokinetic characteristics of euploid embryos in patients with advanced maternal age (AMA)? Summary answer GH supplementation improved the probability of obtaining euploid blastocysts in women with AMA, while did not affect the morphokinetic parameters of the euploid embryos. What is known already Studies have demonstrated that supplementation with GH during ovarian stimulation (OS) has positive impact on the clinical outcomes of in vitro fertilization (IVF). However, few studies have investigated the association of GH supplementation with the ploidy status of embryos. Meanwhile, it is unclear whether GH supplementation affects the morphokinetic signatures and the transfer outcomes of euploid blastocysts. Therefore, the underlying reason for the effect of GH on IVF outcomes remains largely unknown. Study design, size, duration This is a single centre open-labelled randomized controlled trial conducted at single IVF center from August 2022 to August 2023. A total of 441 patients were screened for eligibility and 309 patients were enrolled and allocated. The primary outcome was the proportion of cycles which obtained euploid blastocysts. Secondary outcomes included euploid blastocyst rate per cohort, euploid blastocyst rate per cycle and morphokinetic parameters of euploid embryos obtained with or without GH supplementation. Participants/materials, setting, methods A total of 309 patients aged 38–46 years who underwent their first preimplantation genetic testing for aneuploidy (PGT-A) cycle using antagonist protocol were randomized into the GH group or the control group at 1:1 ratio, with all embryos cultured in the time-lapse monitoring system. Patients in the GH group received 2 IU/day subcutaneous GH from the 2nd day of the previous menstrual period until the day of trigger, for a total of approximately 6 weeks. Main results and the role of chance The baseline and cycle characteristics between the two groups were similar. The proportion of cycles which obtained euploid blastocysts was significantly higher in the GH group (44.74% vs 31.85%, p = 0.02). The GH group had a significantly higher euploid blastocyst rate per cohort (38.46% vs 28.01%, p = 0.01) and mean euploid blastocyst rate per cycle (per biopsy cycle 0.38±0.43 vs. 0.26±0.39, p = 0.02; per OS cycle 0.29±0.41 vs. 0.19±0.36, p = 0.03). Multivariate logistic regression indicated GH supplement was an independent factor for acquisition of euploid embryos (adjusted risk ratio=1.79, 95%CI [1.06-2.99], p = 0.03). We did not observe a statistically significant difference in the morphokinetic parameters and transfer outcomes of the euploid embryos acquired with or without GH supplemented. Limitations, reasons for caution This was a single center study which limited the sample size, further limiting the number of patients with euploid blastocysts analyzed for the morphokinetic parameters and transfer outcomes. Meanwhile, affordability may also introduce selection bias since patients were required to pay for GH. Wider implications of the findings Our research presents new evidence that GH supplementation AMA patients increased the probability of obtaining euploid blastocysts, and explains the underlying reason for the positive effect of GH on IVF outcomes in existing studies. The effect of GH on morphokinetic parameters and transfer outcomes of euploid embryos warrants further investigation. Trial registration number NCT05447208, www.clinicaltrials.gov.

Study of heart rate and corticosterone variability in the simulation of rhino-surgical interventions in biological objects.

Aims: to assess changes in the time range of heart rate variability (HRV) and plasma corticosterone concentration in rats after simulating septoplasty. Materials and methods: a septoplasty was simulated in 30 mature male Wistar rats weighing 210-290 g. An ECG was recorded with subsequent analysis of the time domain of HRV, as well as blood sampling for changes in the concentration of corticosterone in the blood plasma. Results: SDNN significantly increased in comparison with the control on days 2 and 3 (p &lt;0.001), but decreased on days 4-5 (p &lt;0.001) and 6 days (p &lt;0.01 ). rMSSD changed in waves with two irregular peaks on days 1 and 6. SDNN / rMSSD, in comparison with the 1st day of the postoperative period, increased on the 2nd day and continued to grow (p &lt;0.05), and on the 4th day it began to decrease (p &lt;0.01). The total power of HRV was low throughout the postoperative period (p &lt;0.001), except for the 3rd day, when it was equal to the control data. The increase in the total power indicator fell on the 3rd day after the operation (p &lt;0.01), after which its decline occurred again. The concentration of corticosterone in the blood plasma in rats was significantly higher than before (p &lt;0.001). From the 2nd to the 4th postoperative day, its plateau was determined. Conclusion: Simulation of septoplasty leads to changes in the time range of HRV, an increase in the concentration of corticosterone in the blood plasma in rats with its maximum at the time of surgery and after 24 hours, the formation of a "plateau" from the 2nd to the 4th postoperative days, which coincides with changes of HRV.

Is There a Direct Effect Between the Plication of the Myoaponeurotic Layer and the Force of Inspiratory and Expiratory Muscles After Abdominoplasty?

Abdominoplasty may generate an increase in the intra-abdominal pressure (IAP) and consequently an alteration in the pulmonary ventilation. The purpose of this study was to evaluate the potential alterations in the maximal static inspiratory pressure (MIP) and maximal static expiratory pressure (MEP) after abdominoplasty. Thirty-three female patients, aged between 18 and 60, with type III/B Nahas abdominal deformity that underwent abdominoplasty with plication of the anterior rectus and external oblique aponeurosis were selected. The MIP and MEP were measured using a mouthpiece. This is a simple way to indirectly gauge inspiratory and expiratory muscle strength. Measurements were performed before surgery and on the 2nd, 7th, 15th, and 180th postoperative day. In addition, IAP was measured before abdominoplasty and after the placement of compression garment. The MIP and MEP were compared using analysis of variance, followed by the Bonferroni multiple comparison test pairing the different points in time. Paired Student's t test was used for comparing IAP measurements. Pearson's correlation test was used to compare MIP and MEP variations with IAP variation. Results were considered statistically significant when P ≤ 0.05. A decrease was observed in MEP on the 2nd day, with a return close to normal values on the 15th day. In opposition MIP had a surprisingly increase on the 15th postoperative day (129 cmH2O), normalizing 180 days after the operation. A leap in IAP values was revealed at the end of the surgical procedure. It was not possible to establish a positive correlation between the increase of IAP and the alterations of MIP and MEP. There is a decrease in maximum expiratory pressure on the very early postoperative day (2nd postoperative day) and an increase in maximum inspiratory pressure on the 15th postoperative day in patients who underwent abdominoplasty. There was no correlation between the IAP and maximum respiratory pressure variations, both inspiratory and expiratory.

The Efficacy of Ketorolac Buccal Infiltration Following Surgical Removal of The Impacted Mandibular Third Molar on Postoperative Pain and Trismus

Surgical extraction of the mandibular third molars are widely carried out in dental practice. The procedure is associated with postoperative complications such as pain and trismus. Objective: The study aimed to assess ketorolac's analgesic and anti-inflammatory efficacy after surgical extraction of the mandibular third molar. Methods: The study was designed as a double-blinded, randomized prospective clinical study in which 44 patients who required surgical removal of an impacted mandibular third molar were included. They were randomly distributed into two groups (the study and the control/placebo groups), with 22 patients in each group. Immediately after the last stitch, the study group received 30mg/1 ml of ketorolac, while the control group received 1 ml of normal saline at the buccal mucosa near the extraction site of both groups. The mouth openings of the patients were recorded preoperatively, and on the 2nd and 7th postoperative days, a comparison between the two groups was made. The pain level was assessed postoperatively using the numeric rating scale. Results: The comparison between the two groups by pain score showed that there was a statistically significant difference (P = 0.001) in postoperative pain between the study and control groups at all times after the operation. Regarding the trismus, there was no significant difference (p&gt;0.05) between both groups on the 2nd and 7th postoperative days. Conclusion: Ketorolac buccal infiltration is effective for postoperative pain following third molar surgery but has no significant effect on trismus.

Validated Chromatography Method for Analysis of Formaldehyde Migration Levels in Bottled Drinking Water

Polyethylene terephthalate (PET) is utilized in the containment of potable water, nonetheless, it is susceptible to impairment due to temperature and duration of storage. Migration of formaldehyde from PET arises as a consequence of thermal deterioration. This study aims to ascertain the extent of formaldehyde transference in PET-contained drinking water of varying condition, subjected to diverse temperature setting and storage durations. An examination into the levels of formaldehyde migration in polyethylene terephthalate (PET) bottled drinking water was effectively carried out employing a validated high-performance liquid chromatography (HPLC) technique. A total of 162 water samples from three different PET bottled water brands sourced from supermarkets in Palu City, Central Sulawesi, Indonesia, underwent analysis. The formaldehyde assessment was executed utilizing a mobile phase composition of methanol:acetonitrile:water (48:12:40 v/v) for 12.97 minutes at a flow rate of 0.8 mL/minute on the 1st day, the 14th day, and the 42nd day while stored at room temperature and exposed to sunlight. Formaldehyde, lacking effective chromophoric entities and not readily ionizable, necessitated derivatization with 2,4-dinitrophenylhydrazine before HPLC analysis. The findings of the study demonstrated exceptional method linearity within the concentration span of 0.5 to 1321 µg/mL, exhibiting a commendable correlation coefficient of 0.999. The limit of detection (LOD) and quantification (LOQ) were determined to be 17.33 and 57.76 µg/mL, correspondingly. Precision evaluations displayed average intraday and interday values of 128.46±3.48% and 103.19±0.12%, respectively (%RSD &lt; 2/3 CV Horwitz ratio). The intraday and interday %recovery values were computed at 97.22±3.48% and 96.83±0.14% (n = 6). The scrutiny of formaldehyde concentrations in the water samples unveiled the absence of formaldehyde migration.

This case report aimed to contribute to the literature on the successful treatment of fracture of the olecranon with an external fixator in a 4-months-old young cat.

The prevention of infectious complications of caesarean section in the context of the global rise of antibiotic resistance

In the context of the global rise of antibiotic resistance, optimising the prevention of infectious complications of caesarean section (CS) with a reassessment of the guidelines for ultra-short antibiotic (AB) regimens is becoming increasingly important. Given the current data on the negative consequences of the use of AB in pregnant women for the fetal microbiota, the role of antiseptics that are used locally, do not pass to the child, and are less likely to cause resistance, have a wider range of antimicrobial activity is increasing.The objective: to provide clinical evidence for the prevention of infectious complications of CS by topical application of an antiseptic with decamethoxin.Materials and methods. A comparative study of two homogeneous groups of women with low infectious risk delivered by elective CS was conducted. In the 1st group (55 women) an antiseptic with decamethoxin was used at all stages of abdominal delivery: preoperative treatment of the skin and vagina, intraoperative irrigation of the inner surface of the uterus, uterine sutures, and subcutaneous tissue. The 2nd group (55 patients) received conventional antibacterial prophylaxis. In the course of clinical and microbiological parallels, ultrasound monitoring of uterine involution, the results of the examination on the 42nd day after CS and information on the condition of the newborn child were used.Results. The absence of infectious complications of puerperium, infection of the surgical site, trends and signs of inflammatory reactions in both groups was revealed.In the 2nd group 5.5% of patients had partial skin suture separation due to seroma formation and transient infiltration of the subcutaneous tissue. The absence of such phenomena in the 1st group should be considered a consequence of the cytoprotective effect of decametoxin. The use of an antiseptic with decametoxin has pharmacoeconomic advantages over antibiotic prophylaxis regimens.Conclusions. The use of antiseptic with decametoxin in the perioperative care of caesarean section combines the possibility of safe reduction of antibiotics, effective antiinfective protection with guaranteed safety for the child.

Late-onset lethal complication of non-surgically managed massive gastric conduit necrosis after esophagectomy: a case report

BackgroundGastric conduit necrosis (GCN) after esophagectomy is a serious complication that can prove fatal. Herein, we report a rare case of GCN with a severe course that improved with conservative treatment.Case presentationWe present the case of a 78-year-old male patient who underwent an Ivor Lewis esophagectomy and developed a massive GCN. The patient was critically ill in the initial phase but recovered quickly; he also had a ruptured gallbladder and a bleeding jejunal ulcer. On the 22nd postoperative day, massive GCN was revealed on endoscopy. Considering the recovery course, careful observation with a decompressing nasal gastric tube was the treatment of choice. The GCN was managed successfully, having been completely replaced by fine mucosa within 9 months postoperatively. The patient completed his follow-up visit 5 years after surgery without any evident disease recurrence. Five and a half years after the surgery, the patient presented with progressive weakness and deterioration of renal function. Gastrointestinal endoscopy revealed a large ulcer at the anastomotic site. Three months later, computed tomography revealed a markedly thin esophageal wall, accompanied by adjacent lung consolidation. An esophagopulmonary fistula was diagnosed; surgery was not considered, owing to the patient’s age and markedly deteriorating performance status. He died 2013 days after the diagnosis.ConclusionsMassive GCN after esophagectomy often requires emergency surgery to remove the necrotic conduit. However, this report suggests that a conservative approach can save lives and preserve the gastric conduit in these cases, thereby augmenting the quality of life.

Effect of electroacupuncture on autophagy of ovarian granulosa cells in rats with premature ovarian insufficiency

To observe the effects of electroacupuncture (EA) on the autophagy of ovarian granulosa cells in rats with premature ovarian insufficiency (POI), and explore the mechanism of EA in improving POI. Thirty-two female SD rats were randomly divided into a blank group (n=8) and a model making group (n=24). The rats in the model making group were injected intraperitoneally with cyclophosphamide for 15 days to establish the POI model (the dosage on the 1st day was 50 mg/kg, and 8 mg/kg from the 2nd day to 15th day). The successfully modeled rats were then randomly divided into a model group, an EA group, and an estradiol (E2) group, with 8 rats in each group. Rats in the EA group received EA at bilateral "Gongsun" (SP 4) with continuous wave, frequency of 2 Hz, and current intensity of 0.1 to 1 mA, 20 min per treatment, once daily for 14 days. Rats in the E2 group were administered with E2 (0.01 mg/mL) by gavage (10 mL/kg), once daily for 14 days. The changes in estrous cycle were observed by rapid Giemsa staining before and after modeling. After intervention, ovarian tissue morphology was observed by HE staining; serum levels of follicle-stimulating hormone (FSH), E2, anti-Mullerian hormone (AMH), and inhibin B (INHB) were detected by ELISA; immunofluorescence staining was used to observe the expression of p62 in ovarian granulosa cells; the ultrastructure of ovarian granulosa cells was observed by transmission electron microscopy, and the number of autophagosomes and autolysosomes was compared; Western blot and real-time fluorescence quantitative PCR were used to detect the protein and mRNA expression of p62, Beclin-1, and microtubule-associated protein 1A/1B-light chain 3 (LC3) in ovarian tissue. The results of vaginal smears in the blank group showed regular cyclical changes; the rats in the model group showed prolonged estrous cycle or cycle arrest, mostly in proestrus or metestrus, with overall ovarian atrophy, disordered structure, and decreased granulosa cells. Compared with the blank group, rats in the model group showed increased serum FSH level (P<0.01), decreased serum levels of E2, AMH, and INHB (P<0.01), decreased positive expression of p62 in ovarian granulosa cells (P<0.01), with obvious swelling of ovarian granulosa cells, mild to moderate swelling of mitochondria, slight expansion of rough endoplasmic reticulum, and hypertrophy of Golgi apparatus; the number of autophagosomes and autolysosomes in the ovaries was increased (P<0.01), the expression of p62 protein and mRNA was decreased (P<0.01), and the expression of Beclin-1 and LC3 protein and mRNA in ovarian tissue was increased (P<0.01). Compared with the model group, rats in the EA group and the E2 group showed decreased serum FSH levels (P<0.01), increased levels of E2, AMH, and INHB (P<0.01), increased positive expression of p62 in ovarian granulosa cells (P<0.01), alleviated degree of ovarian granulosa cell damage, with relatively intact organelle morphology, and decreased number of autophagosomes and autolysosomes in the ovaries (P<0.01); the rats also showed increased expression of p62 protein and mRNA (P<0.01), and decreased expression of Beclin-1 and LC3 protein and mRNA (P<0.01) in ovarian tissue. EA at "Gongsun" (SP 4) could improve ovarian reserve function in POI rats by reducing the number of autophagosomes and autolysosomes, up-regulating p62 expression, and down-regulating Beclin-1 and LC3 expression, thus inhibiting autophagy of ovarian granulosa cells, and regulating the serum levels of FSH, E2, AMH, and INHB.
