Effect of Management of Grassland on Prey Availability and Physiological Condition of Nestling of Red-Backed Shrike Lanius collurio.

The study aimed to determine the influence of grassland management on the potential food base of the red-backed shrike Lanius collurio and the condition of chicks in the population inhabiting semi-natural grasslands in the Narew floodplain. The grassland area was divided into three groups: extensively used meadows, intensively used meadows fertilised with mineral fertilisers, and intensively used meadows fertilised with liquid manure, and selected environmental factors that may influence food availability were determined. Using Barber traps, 1825 samples containing 53,739 arthropods were collected, and the diversity, abundance, and proportion of large arthropods in the samples were analysed depending on the grassland use type. In the bird population, the condition of the chicks was characterised by the BCI (Body Condition Index) and haematological parameters (glucose level, haemoglobin level, haematocrit, and H:L ratio). The diversity of arthropods was highest in extensively used meadows. Still, the mean abundance and proportion of arthropods over 1 cm in length differed significantly for Orthoptera, Hymenoptera, Arachne, and Carabidae between grassland use types, with the highest proportion of large arthropods and the highest abundance recorded in manure-fertilised meadows. The highest Body Condition Indexes and blood glucose levels of nestlings indicating good nestling nutrition were recorded in nests of birds associated with extensive land use. The H:L ratio as an indicator of the physiological condition of nestlings was high on manure-fertilised and extensively managed meadows, indicating stress factors associated with these environments. This suggests that consideration should be given to the effects of chemicals, such as pesticides or drug residues, that may come from slurry poured onto fields on the fitness of red-backed shrike chicks.

Karakterisasi Alat Filtrasi Air Portable Berdasarkan Variasi Jumlah Absorber Karbon Aktif Limbah Tongkol Jagung

Sumbawa Regency is an area with soil water content containing lime. There was even lime blockage in the pipe holes used. So this research aims to create a portable filtration device that is cheap and efficient. The aim of this research is to characterize a portable water filtration device with an innovative absorber from corncob waste. The way this research works is the process of carbonizing corn cob waste and then activating it using 0.5 M NaOH for 24 hours. The absorber is then filled into a portable filter with dimensions of 50 cm in length and 4 inches in diameter. Filtration is carried out by flowing the collected well water into the water reservoir through a filter. Tests are carried out on water that has not been passed through a filter. After that, characterization was also carried out on the water that had passed through the filter. This characterization consists of Total Dispended Solid (TDS), Temperature, pH, Ca levels, and turbidity. The TDS value obtained decreases with the increasing number of absorbers used, namely from 203, 163, to 123 ppm. In addition, the temperature of the test water has almost no change. The resulting results were temperatures of 32, 33, and 32oC. The resulting pH value shows a decrease with an increase in the number of absorbers used, namely from 8.3; 7.7; 7.3. For turbidity, there was a decrease in the turbidity rate with an increase in the number of absorbers used, namely from 0.29 NTU to 0.3 NTU, and 0.28 NTU. In addition, CaCO3 levels decreased with an increase in the number of absorbers used, namely from 330 mg/l, 290 mg/l, and 240 mg/l. This value has met the threshold set by PMK No. 32 of 2017.

Life Cycle Characteristics and Distribution of Giant Grenadier Coryphaenoides pectoralis (Macrouridae) in Northwest Bering Sea

The outcomes from the survey research in distribution of the giant grenadier Coryphaenoides pectoralis at different stages of development in the Northwest Bering Sea over 1963–2020 have been reported. The data for 37 thousand catches performed with the bottom and multi-depth trawls at the depths between 0–1200 m are processed. It has been revealed that the species fish tend to spawn throughout the year, with two periods of peak spawning activity in the second half of a spring season and from the late summer season to the first half of an autumn season. The female fish ready to spawn migrate down the water column, keeping deeper than 600 m, where the males ready to spawn are concentrated. After spawning, they come back to the feeding areas of less water depths. The juvenile giant grenadier less than 30 cm in length can be encountered in the mesopaelagic and upper bathypelagic zones, which do not appear to form dense aggregations. The majority of the specimens less than 30–40 cm in length and smaller commonly leave this water column layer to occupy the bottom water layers along the continental shelf. Such differentiation between the juvenils and the sexually mature specimens can provide the opportunity to avoid cannibalism and to use the habitat food sources efficiently.

Early diagnosis and management of inseparable conjoint twins. A low-middle-income country experience

HIGHLIGHTS Conjoined twins have captivated mankind for centuries due to the rarity of this birth type; nonetheless, physicians have constantly encountered difficulties in dealing with conjoined twins. Early diagnosis of conjoined twins during prenatal examination is critical for ascertaining the prognosis of the fetus, guiding parental counseling over appropriate courses of action, and potentially enabling the termination of the pregnancy. First-trimester ultrasonography and MRI are complementary modalities in determining the diagnosis and prognosis of conjoined twins in early pregnancy. ABSTRACT Objectives: To discuss the crucial early diagnosis of conjoined twins to determine the type and prognosis. Case Report: A 27-year-old woman was referred to the type A referral hospital with suspicion of congenital abnormalities at 17 weeks of pregnancy. Ultrasound results showed intrauterine monochorionic monoamniotic twins with babies fused on their heads to the urogenital part. The MRI showed a craniopagus, suspected meningomyelocele, and severe bilateral hydronephrosis in the second baby. Due to non-separable cases and a bad prognosis for the fetus, the pregnancy was terminated using misoprostol induction and inserting a balloon catheter. The fetus is born weighing 400 g and 20 cm in length. Conjoined twins obtained the rostral type: a fused head with two faces, a fused thorax until the lower abdomen with one umbilicus, and two pairs of hands and feet. The diagnosis of conjoint twins becomes a problem in early pregnancy, mostly in developing countries. Early diagnosis of conjoined twins during prenatal examination is critical for ascertaining the prognosis of the fetus, guiding parental counseling over appropriate courses of action, and potentially enabling the termination of the pregnancy to prevent maternal stress and complications. Conclusion: Conjoined twins should be identified as soon as feasible to establish the best course of management for both mother and fetus. Ultrasonography and MRI are modalities for determining the diagnosis and prognosis of conjoined twins.

Rapunzel syndrome’s silent cry: addressing neglect and psychiatric factors in pediatric cases

IntroductionRapunzel syndrome is a very rare form of trichobezoar. It is strongly linked to psychiatric conditions; trichotillomania and trichophagia. These conditions in the pediatric population point to the presence of childhood stressors like child neglect, abuse, etc. This case report highlights that child neglect may be an underlying contributing factor in selected cases of Rapunzel syndrome. Hence, a multidisciplinary approach should be sought in all cases of Rapunzel syndrome, catering to the emotional and psychological needs of the pediatric population.Case presentationA 7-year-old girl from a low socioeconomic background presented with periorbital and facial swelling, abdominal distension, and pallor. On physical examination, she showed bilateral pitting edema and a distended abdomen with poor overall hygienic condition. Her family history was positive for Wilson’s disease. Lab investigations highlighted iron deficiency anemia (Hb 8.2 g/dL), with normal liver function. Ultrasound demonstrated ascites, liver changes, and pleural effusion. The work-up for Wilson’s disease was unremarkable. During the hospital course, her abdominal distention lessened; a non-tender epigastric mass (4 × 5 cm) was thus discovered. An abdominal X-ray revealed an entangled mass outlining the gastric shadow. Her parents also revealed a history of trichophagia. Suspecting a large trichobezoar, a laparotomy was performed. After the midline incision, the stomach was opened anteriorly between stay sutures along the curvature. It delivered a large trichobezoar, 65 cm in length extending up to the proximal jejunum. Rapunzel syndrome diagnosis was finally established.ConclusionThis unique presentation emphasizes the need to consider this rare etiology, even with unusual clinical histories especially with a history of child neglect, while collaborative surgical interventions facilitate successful outcomes.

First Report of Shoot Blight of Grapevine Caused by Sclerotinia sclerotiorum in Illes Balears, Mallorca, Spain.

In 2021, grapevines (Vitis vinifera L.) cv. Callet growing in a commercial vineyard located at Pollença (northeast of the island of Majorca, Spain) showed severe symptoms of shoot blight during spring and early summer, with an incidence of 70%. Symptoms consisted of elongated cankered-like lesions, surrounded by water-soaked darker tissues, that developed at the base or around the middle nodes of the shoot. For fungal isolation, shoot samples with lesions were collected, surface disinfected with 2% NaCl for 90s, rinsed twice with deionized water and placed in Petri plates containing potato dextrose agar (PDA). The plates were incubated at 25°C under 12 h light-darkness for 6 days. Isolations consistently yielded on kind of fungal colonies that produced white mycelium and black spherical to elongated sclerotia (2 to 10 mm in diameter). Morphological characterization was consistent with the description of Sclerotinia sclerotiorum (Lib.) de Bary (Bolton et al. 2006). Three isolates (UIB 118-1, UIB 118-26, and UIB 129-41) were preserved and deposited in the Culture Collection of Microbiology-Faculty of Sciences, University of Balearic Islands, Spain. Genomic DNA was extracted from isolates UIB 118-26 and UIB 129-41 using the EZNA Miniprep Kit (Omega Bio-Tek, Norcross, GA). The internal transcribed spacer (ITS) region of ribosomal DNA, β-tubulin (BTUB) and calmodulin (CAL) gene regions were amplified using ITS1F-ITS4 (Gardes and Bruns, 1996; White et al. 1990), Bt-2a/Bt-2b (Glass and Donaldson 1995) and CAL228F/CAL737R (Carbone and Kohn 1999) primer sets, respectively. Amplicons were sequenced and deposited in GenBank with accession numbers MZ604647 and MZ604648 for ITS, OK634402 and OK634403 for BTUB and OK634404 and OK634405 for CAL. BLASTn search showed that isolates were >99 % (ITS, BTUB and CAL) identical to S. sclerotiorum GenBank accession no. KF859933, CP017815 and KF871381, respectively. Pathogenicity tests were conducted using eight one-year old grapevines cv. Cabernet Sauvignon. Old and new green shoots were inoculated by inserting a 6-mm plug of mycelium taken from actively growing cultures on PDA into cuts made at the base and at the distal part of each shoot with a sterile scalpel with a total of eight inoculation points per plant. Inoculated wounds were sealed with Parafilm tape to avoid rapid dehydration. Inoculated plants and an equal number of wounded but non-inoculated plants (negative controls) were maintained at 25 ± 1°C for 48 h in plastic containers to ensure a high relative humidity (>90%). After 5 days, the infection girdled and rotted the green new shoots, whereas the older partially lignified shoots developed a localized long brown lesion that reached 16 cm in length. Due to the rotting of the basal part of the petiole, leaves turned gray, wilted, and died, easily detaching from the stem. In advanced stages of the disease, 7 days after infection, branches died and fell with the leaves remained attached (Fig 1 A, B). Reisolations from diseased shoots were successfully performed on PDA to fulfill Koch's postulates. S. slerotiorum was previously reported on grapevine causing shoot blight in Chile (Latorre and Guerrero, 2001), Korea (Jong-Han et al. 2009), California-USA (Boland and Hall, 1994) and Australia (Hall et al. 2002). AlsoS. sclerotiorum was reported among the endophytic mycobiota associated with Vitis vinifera in the Iberian Peninsula (Gonzalez and Tello, 2011) but not as a pathogen causing visible symptoms on that crop. So, this is the first report of the occurrence of S. slerotiorum as a pathogen of grapevines in Spain causing symptoms of canker and shoot blight. This finding highlights a potential risk of this fungal disease for the wine industry in the Mediterranean region and specially for Spain, the country with the largest acreage devoted to grapevines. Although chemical and biological are suitable control strategies, disease management is difficult as sclerotia of Sclerotinia can remain in the soil for up to eight years (Adams and Ayears, 1979), and preventive surveys are greatly recommended as an important epidemiological tool to monitor the epidemiology of disease and identify potential outbreaks of this new pathogen on grapevine in Spain.

New Benthic Fossils from the Late Ediacaran Strata of Southwestern China

AbstractThe Jiangchuan Biota from the Jiucheng Member (Mb.) of the Dengying Formation (Fm.), discovered in Jiangchuan, eastern Yunnan, China, is marked by copious macrofossils at the apex of the Ediacaran strata. This fauna features benthic algae with varied holdfasts and other fossils of indeterminate taxonomic affinity and is compositionally unique compared to the Shibantan and Gaojiashan biotas of the Dengying Fm. and the Miaohe and Wenghui biotas of the Doushantuo Fm., elsewhere in China. One novel benthic saccular macroalgal fossil, named here Houjiashania yuxiensis gen. and sp. nov., from the Jiangchuan Biota is based on fossils that are sausage‐shaped, elongate, tubular, ranging from 0.3 to 4 cm in length, and up to 0.8 cm in diameter. One terminus is blunt and rounded to an obtuse angle, the other is bent with a spread‐out surface resembling a holdfast, suggesting a three‐dimensional thallus. Thin, stipe‐shaped outgrowths, likely vestiges of sessile saccular life forms, are prevalent in macroalgal fossils of analogous size and shape, as well as present brown algae Scytosiphonaceae, such as Colpomenia and Dactylosiphon. The new findings augment the diversity of benthic algae, such as those known from the Early Neoproterozoic Longfengshan Biota in North China. The benthic algal macrofossils in the Jiucheng Mb. add to knowledge of Late Ediacaran metaphyte diversification and offer more clues about the evolutionary positioning of primitive macroalgae. The co‐occurrence of numerous planktonic and benthic multicellular algae and planktonic microbes might have facilitated ecologically the more extensive later Cambrian explosion evidenced by the Chengjiang Biota in Yunnan.

Effects of cavity resonance and antenna resonance on mode transitions in helicon plasma

Mechanisms of cavity resonance and antenna resonance and their coupling effects on mode transitions in argon helicon plasma excited by a half-helical antenna (14 cm in length) were investigated in this paper. Cavity length was changed to distinguish the effects of cavity and antenna resonances in experiments. Plasma parameters under various discharge conditions, such as input power (0–2500 W), magnetic field (0–1000 G) and cavity length (10–42 cm) were measured. Characteristics of helicon discharges and mode transitions in cases of fixed and continuously changing cavity lengths were compared. The results show that multiple axial eigenmodes (at least five in the present work) were observed in both cases. In fixed-length cavities, the helicon discharge changes abruptly during mode transitions, while in changeable-length cavities, discharge features can change continuously (e.g. in a large range of density from 1.7 × 1012 to 1.3 × 1013 cm−3) without mode transition. Mode transitions also occur as the cavity length increases at fixed input power and magnetic field with periodical variations of plasma parameters. Cavity resonance plays a dominant role in the formation of standing helicon waves of eigenmodes and mode transitions, while antenna resonance significantly affects the transition from inductively coupled modes to helicon wave modes. Enhanced inter-coupling of cavity resonance and antenna resonance appears at specific axial wavelengths of eigenmodes. The threshold conditions for mode transitions were deduced and the overall transition path of wave modes and the corresponding density were predicted quantitatively, which shows that cavity resonance determines the transition path of wave modes, while antenna resonance gives the lower limit of the transition path. Characteristics of helicon discharge and mode transition are closely related to the axial wavenumber. Cavity and antenna resonances influence the helicon discharge and mode transition by determining the axial wavenumber of eigenmodes.

Performance of crustacean and insect meal based diets on the growth and digestive enzyme profile of pearlspot Etroplus suratensis (Bloch, 1790)

A feeding trial of 75 days was conducted in tanks to study the performance of shrimphead meal (SM), crab shell meal (CM) and silkworm pupae meal (SWP) on the growth anddigestive enzyme profile of pearlspot, Etroplus suratensis. Four iso-nitrogenous diets with31.5% crude protein replacing 50% fishmeal (FM) in the diets were formulated viz., SM (T1),CM (T2), SWP (T3) and a control (C). Pearlspot advanced fry, 2 cm in length and 1.1 g inweight, was stocked at 60 nos per tank. After 75 days of the experiment, feed conversionratio (FCR), feed efficiency ratio (FER) and protein efficiency ratio (PER) were observed to besignificantly better (p<0.05) in all treatment groups (T1, T2 and T3) than in control (C). T2 (CM)fed fishes exhibited a maximum specific growth rate (SGR) of 3.25±0.09, and significantlyhigher (p<0.05) weight gain (11.54±0.78 g) than T1, T3 and control. In enzyme assays, T2 (CM) fedfishes exhibited significantly higher (p<0.05) protease activity than other treatments.Lipase activity was significantly higher (p<0.05) in T3. However, there was no significantdifference with control diet-fed fishes. Significantly higher (p<0.05) activities of amylase,malate dehydrogenase (MDH) and lactase dehydrogenase (LDH) were observed in all thetreatments compared with control. The outcomes of the present study indicate that crabmeal (31.5% CP) could be effectively utilised as a 50% replacement for fishmeal in the dietof E. suratensis advanced fry for higher yields.

TRILOCK BRICK : INOVASI DESAIN BATAKO BENTUK SEGITIGA DENGAN SISTEM INTERLOCK

As the construction industry in Indonesia continues to grow, it has significantly impacted the demand for building materials, particularly in the construction sector. One such material is "batako," which is used as a wall filler, along with cement as a bonding material (grout). Therefore, there is a need for a solution that provides easier workability during installation and is cost-effective. The objective of this research is to innovate and analyze the design of triangular-shaped batako with an interlocking system on each side. The methodology used involves experimental testing in a laboratory and follows the Indonesian National Standard (SNI) 03-0349-1989. The process includes material testing, specimen production, compressive strength testing, absorption testing, and a cost comparison analysis. The research resulted in the development of "trilock brick," a triangular-shaped batako measuring 36 cm in length and 9 cm in thickness. The average compressive strength at 28 days was 9,487 MPa, with an average water absorption rate of 5.344%. The installation cost per 1 m2 was Rp. 76,802, with a grout thickness of 0,5 cm. This research demonstrates that this innovation possesses compressive strength and water absorption values comparable to conventional batako. Additionally, trilock brick offers economic advantages with a cost difference of up to 13% compared to conventional batako requirements.

Identification of a Clinical Spirometra mansoni Plerocercoid Isolate Using Molecular and Morphological Data.

Sparganosis has been a neglected parasitic zoonosis for a long time. The accurate identification of Spirometra tapeworms in clinical practice is poorly understood. A case of breast sparganosis was reported in Henan Province of central China. One plerocercoid approximately 3.5cm in length was collected from the patient. The clinical isolate was identified as Spirometra mansoni based on the barcoding sequences of mitochondrial cytochrome c oxidase subunit 1 (cox1). Finally, the epidemiology of sparganosis in central China was reviewed. Comprehensive public health education should be carried out, and the risky habit of eating live tadpoles must be discouraged in Henan Province.

Exploring the dietary and therapeutic potential of licorice (Glycyrrhiza uralensis Fisch.) sprouts.

Ethnopharmacological relevanceThis research substantiates the traditional use of Glycyrrhiza uralensis Fisch. for liver health, with scientific evidence of the non-toxic and lipid-lowering properties of licorice sprout extracts. The sprouts' rich mineral and amino acid content, along with their strong antioxidant activity, reinforce their value in traditional medicine. These findings bridge ancient herbal practices with modern science, highlighting licorice's potential in contemporary therapeutic applications. Aim of the studyThe study aimed to investigate the dietary and medicinal potential of G. uralensis sprouts by assessing their safety, nutritional content, and antioxidant properties using both plant and animal models. Specifically, the study sought to determine the effects of different sizes of licorice sprouts on lipid metabolism in human liver cancer cells and their overall impact on rat health indicators. Materials and methodsThe study examined the effects of aqueous and organic extracts from G. uralensis sprouts of varying lengths on the cytotoxicity, lipid metabolism, and antioxidant activity in HepG2 cells, alongside in vivo impacts on Sprague-Dawley rats, using MTT, ICP, and HPLC. It aimed to assess the potential health benefits of licorice sprouts by analyzing their protective effects against oxidative stress and their nutritional content. ResultsLicorice sprout extracts from G. uralensis demonstrated no cytotoxicity in HepG2 cells, significantly reduced lipid levels, and enhanced antioxidant activities, with the longest sprouts (7 cm) showing higher mineral, sugar, and arginine content as well as increased glycyrrhizin and liquiritigenin. In vivo studies with Sprague-Dawley rats revealed weight gain and improved antioxidant enzyme activities in blood plasma and liver tissues after consuming the extracts, highlighting the sprouts' dietary and therapeutic potential. ConclusionsThis study is the first to demonstrate that G. uralensis sprouts, particularly those 7 cm in length, have no cytotoxic effects, reduce lipids, and have high mineral and antioxidant contents, offering promising dietary and therapeutic benefits.

Identification and Analysis of Micro-Doppler Signature of a Bird Versus Micro-UAV

The groundbreaking advancement of micro unmanned aerial vehicles (micro-UAVs) has been staggering. The diversity of micro-UAV operations is demanding in most sectors. However, the current regulatory framework for the civilian use of these devices is still insufficient. The operation of micro-UAVs may pose risks, including privacy violations and collision hazards. To address these concerns, a radar with advanced processing is needed. This study presents a preliminary design of an S-band continuous wave (CW) radar, which was simulated using MATLAB. The size of the rotating propeller blades of the micro-UAV ranges from 20 to 40 cm in length, while the size of a bird’s flapping wing measures 35 cm in length, comprising 22 cm for the upper arm and 13 cm for the lower arm. The analysis was conducted under hovering conditions, where the target's main body is stationary while its micro-parts move continuously. The Short-Time Fourier Transform (STFT) analysis successfully identified the unique signature of both targets. The results showed that the S-band CW radar design at 5 GHz is effective in extracting the micro-Doppler signature of a bird versus a micro-UAV. The extracted features can be used as additional characteristics for target classification in the future.

Effects of culture salinity on growth and reproduction of the polychaete Dendronereis chipolini

Dendronereis chipolini is an important brackish water polychaete and has been wildly used as fattening feed for marine shrimp broodstocks. Investigation into the effects of salinity on performance of this worm species is fundamental for the development of mass culture procedure to produce feed for fattening shrimp broodstock and reduce pressure on wild catch. The study was conducted in a tank system with an area of 0.25 m2 in which the young worms (0.9±0.2 cm in length and 0.007±0.003 g in body weight) were stocked at 100 inds/tank. Four salinity treatments, including 15, 20, 25, 30 ppt, were designed with three replicates each. The worms were fed once a day at 9 am with commercial shrimp feed at a rate of 3% body weight. After 150 days of rearing, the fastest growth of worms was recorded in 20 ppt. The survival rate was also higher in 20 ppt but no significant difference was found (p>0.05) between treatments. Higher absolute fecundity (103,890±17,389 and 112,740±22,328 eggs/female) was recorded at 20 and 25 ppt, respectively. The males in 20 ppt also produced a higher number of sperms. Overall, the polychaete D. chipolini reared at 20 ppt performed higher growth, survival and reproduction rates.

Complex floral morphology and scent chemistry mediate hawkmoth pollination of an African orchid in the diverse Habenaria clade

Abstract One explanation for the evolution of complex floral morphology in orchids is that it can function as a component of ‘lock-and-key’ mechanisms that ensure pollen transfer by specific flower visitors. We investigated the roles of floral morphology and scent in the pollination of Bonatea antennifera, an African orchid that is phylogenetically embedded in the hyper-diverse Habenaria clade. Using camera traps and direct observations, we established that B. antennifera is pollinated by an assemblage of short-tongued hawkmoths with proboscides ~4 cm in length, corresponding to the spur length of the orchid. Pollinaria are attached between the palps of these hawkmoths via an intricate mechanism involving a wedge-shaped rostellum chamber and a tooth in the floral spur that deflect the head and proboscis of the hawkmoth to either side of the spur entrance. This functional subdivision of the flower results in removal of a single pollinarium per visit. Scent production is synchronized with the peak activity of hawkmoths at dusk, and electrophysiology experiments showed that hawkmoth antennae respond to several of the dominant volatile terpenoid compounds [e.g. R-(−)-linalool, caryophyllene epoxide, and (E)-nerolidol] emitted by the flowers. These results illustrate the functional significance of complex floral morphology and scent for pollen transfer in orchids.

Comparing methods for determining the metabolic capacity of lumpfish (Cyclopterus lumpus Linnaeus 1758).

Lumpfish (Cyclopterus lumpus) mortalities have been reported during the summer at some North Atlantic salmon cage-sites where they serve as "cleaner fish." To better understand this species' physiology and whether limitations in their metabolic capacity and thermal tolerance can explain this phenomenon, we compared the aerobic scope (AS) of 6°C-acclimated lumpfish (~50 g and 8.8 cm in length at the beginning of experiments) when all individuals (N = 12) were given a chase to exhaustion, a critical swim speed (Ucrit) test, and a critical thermal maximum (CTMax) test (rate of warming 2°C h-1). The Ucrit and CTMax of the lumpfish were 2.36 ± 0.08 body lengths per second and 20.6 ± 0.3°C. The AS of lumpfish was higher during the Ucrit test (206.4 ± 8.5 mg O2 kg-1 h-1) versus that measured in either the CTMax test or after the chase to exhaustion (141.0 ± 15.0 and 124.7 ± 15.5 mg O2 kg-1 h-1, respectively). Maximum metabolic rate (MMR), AS, and "realistic" AS (ASR) measured using the three different protocols were not significantly correlated, indicating that measurements of metabolic capacity using one of these methods cannot be used to estimate values that would be obtained using another method. Additional findings include that (1) the lumpfish's metabolic capacity is comparable to that of Atlantic cod, suggesting that they are not as "sluggish" as previously suggested in the literature, and (2) their CTMax (20.6°C when acclimated to 6°C), in combination with their recently determined ITMax (20.6°C when acclimated to 10°C), indicates that high sea-cage temperatures are unlikely to be the primary cause of lumpfish mortalities at salmon sea-cages during the summer.

A retrospective cohort study of autogenous iliac strut bone grafting in large bone defects of the lower extremity

Autogenous iliac bone graft (AIBG) is the treatment of choice for managing bone defects, and favorable results have been reported for bone defects < 5 cm in length. In large bone defects ≥ 5 cm, it is difficult to obtain good results with simple bone grafting, and other management options have drawbacks, such as long immobilization periods and high complication rates. We hypothesized that AIBG in the strut form might show favorable results in large bone defects with minimal complications. This study aimed to investigate the outcomes of strut-type AIBG and evaluate its effectiveness compared to cancellous AIBG. This retrospective study included 50 patients who underwent AIBG for bone defects at a single institution between March 2011 and April 2020. We performed corticocancellous AIBG in a strut form to manage bone defects ≥ 5 cm in the lower extremities. The strut bone was harvested along the iliac crest and grafted slightly longer than the bone defect to apply a sufficient compressive force. Demographic information and radiographic and clinical results of patients who underwent strut AIBG (Group S) were analyzed. The outcomes of union, time to union, complications, and reoperation were compared with those of patients who underwent cancellous AIBG (Group C). The study population comprised 37 men (74%) and 13 women (26%), with a mean age of 50.0 (range: 19–78). The average follow-up period was 25.6 months (12–104 months). Group S included 16 patients with a mean bone defect length of 6.8 ± 1.2 cm. In Group S, union was achieved in all patients, with an average time to union of 6.7 months. Complications occurred in four cases, all related to wound problems. Group C comprised d 34 patients with a mean defect length of 2.8 ± 1.1 cm. Complications occurred in five patients in Group C, including four soft tissue problems and one implant failure. When comparing the outcomes of Groups S and C, no significant differences were observed. AIBG is an effective and safe technique for managing bone defects. Strut AIBG can be used effectively for bone defects ≥ 5 cm in the lower extremities.

Iatrogenic Tracheal Rupture after Endotracheal Intubation: A Case Report

Iatrogenic tracheal rupture is very rare condition and has a lot off causes (intubation, tracheostomy, bronchoscopy, esophagectomy), but orotracheal intubation is the most common. Diagnosis is based on the occurrence of symptoms that are not specific but highly suggestive: subcutaneous emphysema, respiratory insufficiency, pneumothorax, and hemoptysis. The appearance of subcutaneous emphysema as a first sign plays a main role for early diagnosis and rapid appropriate treatment. Diagnostic confirmation is possible by chest X-ray, thoracic computed tomography and bronchoscopy which confirmed the size and site of the lesion. Treatment can be conservative, in patients with small ruptures, less than 2 cm, and surgical in the majority of ruptures over 2 cm in length.&#x0D; Our case report presents an iatrogenic post-intubation tracheal rupture treated conservatively. Our patient was a 71-year-old woman, admitted in our hospital with fracture of right humerus for elective surgery. Her medical history was only arterial hypertension. She underwent general anesthesia, intubated with flexible ET tube, positioned in beach-chair position after introduction, and no complication occurred during surgery. 18 hours after surgery, after severe coughing, she suddenly developed subcutaneous emphysema of the facial, neck and upper anterior chest. Tracheal rupture was confirmed with a thoracic computed tomography and tracheobronchial fiber endoscopy. It showed a posterior tracheal transmural rupture 1 cm long, located 4 cm above the carina, covered with small tissue that opened in inspirium. Conservative treatment with antibiotic cover was performed, and the patient was discharged home in good condition, fourteen days after the initial injury.
