BMI gain and dietary characteristics are risk factors of MASLD in non-obese individuals

This longitudinal observational study aimed to evaluate whether cardiometabolic factors and dietary characteristics are determinants of metabolic dysfunction-associated steatotic liver disease (MASLD) in non-obese individuals (body mass index [BMI] < 25 kg/m²). The study was conducted at the Japanese Red Cross Society Kyoto Daiichi Hospital. Clinical data were longitudinally recorded at annual health checks. The diagnosis of MASLD was based on the results of abdominal ultrasonography and cardiometabolic criteria. Lifestyle behaviors and dietary characteristics were assessed using a self-administered questionnaire. A total of 4,100 non-obese middle-aged and older participants (1,636 men and 2,464 women) were followed up for an average of 6.44 ± 4.16 years. During the follow-up period, there were 410 new cases of MASLD in men (25.1%) and 484 in women (19.6%). The incidence rate was higher for men (39.7 per 1,000 person-years) than for women (30.1 per 1,000 person-years). Multivariable-adjusted logistic regression analyses using the rate of change per year with standardized values found that BMI gain was strongly associated with the onset of MASLD for both men (OR: 1.90, 95% CI: 1.64–2.19) and women (OR: 1.95, 95% CI: 1.72–2.21). Increased waist circumference and triglycerides were also associated with MASLD onset for both men and women. Lowering of high-density lipoprotein cholesterol was identified as a risk factor for MASLD in both men and women. Regarding dietary characteristics, the onset of MASLD was significantly and negatively associated with “often eating vegetables” for men (OR: 0.73, 95% CI: 0.57–0.93) and “often eating soy products” for women (OR: 0.71, 95% CI: 0.58–0.88), even after adjusting for BMI change and other covariates. These findings suggest that maintaining body weight and favorable dietary characteristics are key factors in the prevention of MASLD in non-obese individuals.

Characterization of a novel conditional knockout mouse model to assess efficacy of mRNA therapy in the context of severe OTC deficiency.

Ornithine transcarbamylase deficiency (OTCD) is the most common urea-cycle disorder, characterized by hyperammonemia and accompanied by a high unmet patient need. mRNA therapies have been shown to be efficacious in hypomorphic Sparse-fur abnormal skin and hair (Spf-ash) mice, a model of late-onset disease. However, studying the efficacy of ornithine transcarbamylase (OTC) mRNA therapy in traditional knockout mice, a model for severe early-onset OTCD, is hampered by the rapid lethality of the model and poor lipid nanoparticle (LNP) uptake into neonatal mouse liver. We developed a novel tamoxifen-inducible mouse to study the effect of mRNA therapy in the context of complete or near-complete OTC loss in adult animals. Characterization of the model showed that it is highly reproducible, 100% penetrant, and phenocopies hallmarks of human disease, with animals exhibiting decreased body weight, hyperammonemia, and brain edema. Delivery of OTC mRNA increased survival, maintained body weight, delayed the onset of hyperammonemia, and reduced brain edema. Therefore, this model provides a platform to study LNP-mediated mRNA therapies for the treatment of late-onset OTCD.

Save the Saviors: How to Minimize Sudden and Premature Death Among Doctors?

During the past few years, the sudden death of young ophthalmologists in India shocked the entire ophthalmic fraternity. One of the most important reasons is overwork, stress, lack of physical activity, and lack of regular health checkups. Young and middle-aged doctors are in a critical period of their family and professional career development. Not only do they hope to make breakthroughs in clinical services as well as academic research, but they also face pressure from patients and their families. The escalation of contradictions between doctors and patients has also become an increasing mental burden in the practice of many medical professionals. We suggest that each and every ophthalmologist/doctor should take responsibility for his/her own health. Medical professionals/ophthalmologists should regularly perform aerobic exercise or connect with families and friends for support instead of excessive smoking and drinking. Besides, regular medical checkups (blood pressure, blood sugar, ECG, Echocardiography, etc) are an effective approach to detecting and decreasing the risk of some potential diseases such as diabetes, coronary artery disease, hypertension, and stroke. Government, non-government organizations, medical/ophthalmic societies, and media should help to improve the working environment and re-establish doctor-patient trust, which may further decrease the sense of “stress/burnout” for doctors. A change of lifestyle and healthy work-life balance – adding yoga, exercise, and meditation to reduce stress, maintain quality eating, and maintain body weight can save many young doctor/ophthalmologist lives.

NPF and sNPF can regulate the feeding behaviour and affect the growth and antioxidant levels of the rice brown planthopper, Nilaparvata lugens.

Neuropeptide F (NPF) and short neuropeptide F (sNPF) are important neuropeptides and mainly affect feeding behaviour of insects. However, the regulation of insect feeding behaviour by NPF and sNPF appears to differ between species, and it is not clear how NPF and sNPF regulate the food intake of the brown planthopper (Nilaparvata lugens). Therefore, the functions of NPF and sNPF in regulating food intake and affecting the growth and antioxidant levels of N. lugens fed on host rice plants were investigated by knocking down NPF and sNPF respectively and simultaneously knocking down both of them by RNA interference. The results showed that NPF and sNPF were mainly expressed in the head of N. lugens, and N. lugens increased food intake after NPF and sNPF were knocked down, which was reflected in the prolonged duration of N4a and N4b waves in the electrical penetration graph (EPG) experiment after knocking down NPF and sNPF. In addition, knocking down NPF and sNPF led to the increase of body weight and mortality of N. lugens, and also led to the increase of antioxidant level of N. lugens. So it was concluded that NPF and sNPF could regulate food intake, maintain body weight stability and oxidative balance in N. lugens. Our study clarified the molecular mechanism of NPF and sNPF regulating feeding behaviour and affect the growth and antioxidant level of N. lugens.

The protective effect and mechanism of selenium-rich rice-based selenoproteins and sodium selenite against D-galactose-induced aging mice

Rice is among the world's top three food crops and is a staple food for more than half of the world's population. The body cannot directly synthesize selenium, and its deficiency causes different diseases, so consuming selenium-rich rice can supplement the body's selenium requirements. People are paying more attention to food health, and selenium-rich rice is gradually becoming part of people's vision. In this experiment, selenium-rich microcapsules were prepared using selenoproteins extracted from selenium-rich brown rice. These selenoprotein microcapsules demonstrated higher reducing and free radical scavenging ability than bovine serum albumin. In vitro experiments, selenoproteins microcapsules demonstrated 0.93% reducing capacity, 95% DPPH free radical ability, and 58% hydroxyl scavenging ability. Different selenoprotein microcapsules and sodium selenite doses were used to investigate their impact on D-galactose-injected aging mice. Selenoprotein microcapsules helped maintain body weight and alleviated the abnormally elevated organ coefficients. At the same time, a high dose of sodium selenite caused selenosis, organ congestion, edema, and hypertrophic hyperplasia. It was observed that 60 μg kg−1 selenoproteins had a good repairing impact on oxidative damage in the liver and kidneys, improved T-AOC, SOD, and GPx activity, and reduced MDA contents in all organs. In comparison, 100 μg kg−1 selenoproteins led to selenosis, and 30 μg kg−1 was less effective and insufficient in relieving aging effects in mice. The results showed that the proper selenium intake relieves oxidative and biological stress.The study provides basic information about selenoproteins microcapsule preparation from selenium-enriched rice and its application in the health care system.

Chemopreventive potential of goniothalamin in diethylnitrosamine-induced hepatocellular carcinoma through the suppression of P13K/AKT signalling pathway.

Liver cancer is the most lethal form of cancer and carries a high risk of death around the world. Goniothalamin (GTN) is a styryl-lactone that possesses antiproliferative and apoptotic activity. The molecular action of GTN is not yet fully evaluated. Thus, our research has been intended to assess the chemopreventive and apoptotic activities of diethylnitrosamine (DEN)-induced hepatocellular carcinoma (HCC) in rats. Rats were separated into 4 groups: control, DEN only, DEN + GTN (30 mg/kg bw), and GTN (30 mg/kg bw) alone. We evaluated body weight, liver weight, tumor incidence, hepatic toxic markers, antioxidants, inflammatory cytokines, histopathology, immunohistochemistry, and Western blot studies. DEN lessened body weight, antioxidants, and apoptosis, whereas it elevated tumor incidence, toxic markers, cytokines, and Bcl-2 expression. GTN treatment maintains body weight, liver weight, and antioxidant levels, and it also prevents tumor incidence, oxidative stress, toxic markers, pro-inflammatory cytokines, and histological changes. It triggers apoptosis by constraining Bcl-2 and elevating caspase-3 levels. GTN also attenuated the P13K/ AKT signaling which enhanced apoptosis. These findings revealed that GTN subdues the P13K/AKT pathway and has auspicious chemopreventive and apoptotic actions in DEN-induced HCC. Therefore, GTN would be suggested as a new medicine in natural remedies for liver cancer.

Pengaruh Penambahan Tepung Serai Wangi (Cymbopogon nardus L.) sebagai Imbuhan Pakan dalam Ransum terhadap Performa Ayam Jowo Super (Joper)

Ayam Joper stands for Ayam Jowo Super or often known by the public as Ayam Kampung Super. Joper chicken is the result of a cross-breed between male native chickens and laying hens. The Citronella plant is a type of plant from the grass family with bioactive substances, namely essential oils, citronella, geraniol, citral, eugenol, cadine, and cadinol which have the potential to become feed additives. The purpose of this study was to examine the effect of the addition of citronella meal (Cymbopogon nardus L.) as a feed additive in the ration on the performance of Joper. This research was conducted for 63 days from July 26 to September 26, 2023, located in Padasuka Village, Ciomas, Bogor. This study used Joper chickens with an average initial body weight of 34.9 ± 2.71 grams. The design model used in this study is a completely randomized design (CRD) consisting of 5 treatments 4 replicates, each replicate has 5 Joper chickens. The treatments given were R0 = basic ration without the addition of 0% citronella meal, R1 = basic ration with the addition of 2% citronella meal, R2 = basic ration with the addition of 4% citronella meal, R3 = basic ration with the addition of 6% citronella meal, R4 = basic ration with the addition of 8% citronella meal. The results showed that the addition of citronella meal as a feed additive in the ration had an effect (P&lt;0.05) on increasing ration consumption, maintaining body weight gain, and reducing the feed conversion ratio of Joper chickens. The conclusion of this study is the addition of citronella meal in a ration of as much as 6% gives the best results on ration consumption and body weight gain while the addition of citronella meal in the ration as much as 8% the best result on feed conversion ration in week 3 and 7.

Diagnosis of Bulimia Nervosa Based on Dsm V

The purpose of this study was to analyze the diagnosis of bulimia nervosa based on DSM V. The method used in this study was qualitative with a library research approach. This study concludes that bulimia nervosa is a form of an intense fear of gaining weight or refusing to maintain body weight at or above average body weight, at least according to age and height, and experiencing disturbances in how to view one's own weight or body shape. So, it causes various severe complications and can even cause death. Therefore, people with bulimia nervosa need comprehensive medical and psychological treatment, namely hospitalization if necessary and individual and family therapy.

Neurohistopathological Alterations Induced by Clitoria Ternatea and Emblica Officinalis Extracts in Diabetic Male Wistar Rats.

Background Diabetes mellitus is a chronic condition that can lead to significant neurodegenerative complications. The extracts of traditional medicinal plants such as Clitoria ternatea and Emblica officinalis have neuroprotective properties. This study investigates the neurohistopathological alterations in diabetic male Wistar rats treated with these extracts. Objective This study aimed to assess the neuroprotective potential of Clitoria ternatea and Emblica officinalis extracts in mitigating neurohistopathological alterations in streptozotocin-induced diabetic male Wistar rats Methods In this experimental investigation, 48 male Wistar rats, aged 8-12 weeks and weighing 200-250g, were randomly allocated into eight groups (n=6): control, diabetic model, metformin treatment, Clitoria ternatea extract treatment, Emblica officinalis extract treatment, diabetic model + Clitoria ternatea extract treatment, diabetic model + Emblica officinalis extract treatment, and diabetic model + combined extract treatment.Streptozotocin 40 mg/kg was used to induce diabetes. Treatments included 100 mg/kg metformin, 300 mg/kg Clitoria ternatea extract, and 250 mg/kg Emblica officinalis extract. After three weeks, blood glucose levels, body weight, and neurohistopathological parameters (neuronal degeneration, gliosis, and vacuolation) were evaluated. Results The diabetic rats had much higher blood sugar levels (320.4 ± 15.3 mg/dL) and lost a lot of weight (180.7 ± 9.5 g) compared to the control group, which had normal blood sugar levels (92.3 ± 4.8 mg/dL) and stable body weight (225.4 ± 12.1 g) (p < 0.001). Treatment with Clitoria ternatea extract reduced blood glucose to 160.3 ± 12.1 mg/dL, while Emblica officinalis extract lowered it to 155.4 ± 11.8 mg/dL. The combined treatment brought glucose levels closer to normal (110.5 ± 8.9 mg/dL). Similarly, both extracts mitigated weight loss, with the combined treatment maintaining body weight at 220.4 ± 12.0 g, close to the control group (p < 0.05). The study of diabetic rats that had not been treated showed severe neuronal degeneration (4.2±0.4), gliosis (4.5±0.5), and vacuolation (4.7±0.5). Treatment groups showed marked reductions in these parameters, with the combined treatment producing the greatest neuroprotective effects, comparable to controls (p < 0.001). Conclusions Extracts from Clitoria ternatea and Emblica officinalis, particularly when combined, provide significant neuroprotective advantages in male Wistar diabetic rats, significantly lowering hyperglycemia and related neurohistopathological changes. These findings support the potential use of these extracts as complementary or alternative therapies in managing diabetic complications.

Effect of food stimuli presentation on restrained eater's food choice: An ERP study

Restrained eaters are individuals who consciously follow a limited food intake diet to lose or maintain body weight. With the rising numbers of obesity cases, retrained eating has became more prevalent as more people adopt it to cope with obesity. The dual conflict theory states that restrained eaters often encounter conflicting choices of food pleasure and weight management. The present study investigated the difference in food choice regarding different presentations of the weight management goal. The study hypothesized difference in successful and unsuccessful restrained eaters’ food choice when presented with the conflicting food/weight maintenance stimuli. A total of 49 college students participated in the study and the N2, P3 and LPP event-related potentials (ERPs) were investigated during a food choice task. Results showed that the reaction time in unsuccessful restrained eaters (UREs) were greater than successful restrained eaters (SREs). The ERP results showed that SREs exhibited smaller N2 and greater P3 amplitudes than UREs, however, we did not find a difference in LPP amplitudes between the two groups. The findings suggest that the UREs demonstrated greater sensitivity and smaller inhibition to food cues, while we do not have supports for a difference in motivational and emotional salience. This is the first study that investigated the food choice of SREs and UREs when faced with different presentations of conflicting goals, which enriches the theoretical model and provides neural correlates evidence for future studies.

Nutrient Digestive Bypass: Determinants and Associations with Stool Quality in Cats and Dogs

The effect of digestive bypass macronutrients and age on stool quality (moisture and firmness) in dogs and cats is not well understood. Data were analyzed from digestibility tests (n = 2020, 361 dogs and 536 cats) including dry and wet product types. Both food and feces were measured for moisture and nutrients according to standard protocols; stool firmness was graded. Linear mixed modeling was used to evaluate the associations between nutrient bypass, age and stool quality. Bypass protein increased stool moisture (dog, cat p &lt; 0.0001) and decreased firmness (dog p = 0.01, cat p &lt; 0.0001), while bypass fiber decreased stool moisture and increased firmness (dog, cat p &lt; 0.0001 for both). Both species manifested a negative quadratic effect of advanced age on stool firmness (dog p &lt; 0.0001 and cat p = 0.02). However, the association of advanced age (quadratic effect) with metabolizable energy required to maintain body weight was different between species; dogs had a positive association (p = 0.028), while it was negative for cats (p &lt; 0.0001). Taken together, these data may aid in the development of food formulations for companion animals, which can better meet changing nutritional needs across life stages.

291 Isoenergetic reduction of dietary macronutrients changes body composition and physical activity in cats, regardless of body condition, when fed to maintenance

Abstract Commercial extruded cat foods deviate noticeably from the natural diet of wild cats and contain greater carbohydrate and less protein. This alteration in macronutrient distribution is postulated as a potential factor in feline obesity, yet the precise role of carbohydrates in either predisposing to, or treating, obesity in cats remains inconclusive. This study explored the effects of diets differing in protein, fat, and carbohydrates (NFE) on physical activity and body composition when fed to adult male cats to maintain body weight (BW). Three extruded diets were formulated for adult maintenance according to AAFCO in an isoenergetic approach using the same ingredients in varying proportions: low-protein (LP; protein 28% of metabolizable energy [ME], fat 40% ME, NFE 32% ME), low-fat (LF; protein 42% ME, fat 30% ME, NFE 30% ME), or low-carbohydrate (LC; protein 36% ME, fat 41%ME, NFE 23% ME). Lean (n = 9) and obese (n = 9) adult male neutered cats were fed each diet for 4-wk in a 3 x 3 Latin square design. Physical activity was measured via actigraphy on d 15 to 21 of each period. On d 23 total tissue mass (TTM), body fat mass (BFM), lean soft tissue mass (LSTM), and bone mineral content (BMC) were assessed by dual energy x-ray absorptiometry. Daily food intake and weekly BW were recorded. Data were statistically analyzed in SAS Studio via the GLIMMIX procedure with diet and body condition (bc) as fixed effects and cat as subject. A Tukey post-hoc analysis was performed to assess multiple comparisons when significant (P &amp;lt; 0.05). Body weight (Pbc &amp;lt; 0.0001), TTM (Pbc &amp;lt; 0.0001), BFM (Pbc &amp;lt; 0.0001), LSTM (Pbc &amp;lt; 0.0001), and BMC (Pbc = 0.004) were greater in obese compared with lean cats. Regardless of body condition, LSTM was greater in cats consuming the LF diet (P = 0.010). Daily physical activity was similar between lean and obese cats; however, activity as a ratio of light:dark activity was greater for lean cats compared with obese (Pbc = 0.027). Additionally, cats were more active during dark hours when fed LC and LF (Pdiet = 0.016), though no difference was observed for activity during light hours (P = 0.452). These findings support previous observations regarding body composition disparities between lean and obese cats. Contrary to previous reports, no discernible distinctions in voluntary physical activity were noted between lean and obese cats. In previous studies, both high-carbohydrate and high-fat diets reduced voluntary physical activity when fed to maintain BW which was attributed to a potential alteration in mood and energy levels seen in other species. An increase in physical activity in cats consuming the LF diet could suggest a similar pattern. Future research should explore the metabolic implications of varied macronutrient distributions to expand upon the physiological insights presented herein. Funding for this study was provided by Champion Petfoods, Mitacs Accelerate, and the Natural Sciences and Engineering Council of Canada.

Blood pressure alteration associated with abnormal body electrolyte and water balance in colitis mice.

Previous studies reported that there is an association between abnormal body fluid balance and prognosis in colitis patients. However, it remains to be clarified the effects of colitis on characteristics of body electrolytes or water content, including alternation in blood pressure. In this study, we examined the effects of colon injury on body water balance and blood pressure in the dextran sodium sulfate (DSS)-induced colitis mouse model. We evaluated body electrolytes and water content, blood pressure, and urea-associated water conservation in DSS mice. By 5 days after the treatment, DSS mice exhibited diarrhea but relatively maintained body weight and total body sodium, potassium, and water content by increases in water intake and hepatic ureagenesis. On 7 days after DSS treatment, when colitis becomes severe, DSS mice significantly decreased food and water intake, and body weight but significantly increased relative total body sodium, potassium, and water content per dry mass. Notably, DSS induced more total body dry mass loss relative to water loss. These body electrolytes and water accumulation on day 7 were associated with a reduction in urinary osmole excretion and urine volume accompanied by renal urea accumulation. DSS mice significantly increased blood pressure by day 5 and then decreased on day 7. These findings suggest that body electrolyte and fluid imbalance and alternations in blood pressure in colitis vary with the stage and severity of the condition. Assessment and correction of electrolyte and water content at the tissue level would be important to improve the prognosis of colitis.

Anti-Inflammatory Effect of Dietary Pentadecanoic Fatty Acid Supplementation on Inflammatory Bowel Disease in SAMP1/YitFc Mice.

Dietary fats have been linked to the increasing incidence of chronic diseases, including inflammatory bowel diseases (IBD), namely, Crohn's disease (CD). This study investigated the impact of pentadecanoic acid (C15:0), a type of an odd-numbered chain saturated fatty acid, for its potential anti-inflammatory properties in different mouse models of experimental IBD using the SAMP1/YitFc (SAMP) mouse line (14- or 24-week-old), including chronic ileitis and DSS-induced colitis. To quantitively assess the effect of C:15, we tested two dosages of C:15 in selected experiments in comparison to control mice. Intestinal inflammation and intestinal permeability were used as primary outcomes. In ileitis, C:15 supplementation showed an anti-inflammatory effect in SAMP mice (e.g., a reduction in ileitis severity vs. control p < 0.0043), which was reproducible when mice were tested in the DSS model of colitis (e.g., reduced permeability vs. control p < 0.0006). Of relevance, even the short-term C:15 therapy prevented colitis in mice by maintaining body weight, decreasing inflammation, preserving gut integrity, and alleviating colitis signs. Collectively, the findings from both ileitis and colitis in SAMP mice indicate that C:15 may have therapeutic effects in the treatment of IBD (colitis in the short term). This promising effect has major translational potential for the alleviation of IBD in humans.

Dietary Counseling Outcomes in Patients with Lung Cancer in an Upper-Middle-Income Country: An Open-Label Randomized Controlled Trial.

Background: Malnutrition harms treatment outcomes, QoL, and survival in lung cancer patients. Effective dietary counseling can improve nutrition, but few randomized controlled trials have focused on lung cancer patients. The objective of this study was to determine if dietary counseling improves nutritional and treatment outcomes when compared to routine care. Methods: This open-label parallel RCT was conducted at Maharaj Nakorn Chiang Mai Hospital in Thailand. The investigators used computer-generated blocked randomization to assign patients to dietary counseling by a nutritionist or routine care. The nutritionist sessions occurred before treatment, with follow-ups at 3-4 weeks and 12 weeks. The primary outcome was the mean percentage change in the body weight of patients at 12 weeks. Secondary outcomes included changes in the BMI, nutrition score, QoL, serum albumin level, lymphocyte count, energy and protein intake, treatment response, PFS, and OS. Results: Between April 2020 and May 2022, after completing recruitment, 80 lung cancer patients were randomized: 43 to dietary counseling and 37 to routine care. The dietary counseling group showed significant benefits, with smaller decreases in body weight at 3-4 weeks (-0.8% vs. -2.6%, p = 0.05) and 12 weeks (-1.1% vs. -4.3%, p = 0.05). They also had higher energy and protein intake levels and better treatment response rates. The secondary outcomes and significant adverse events did not differ significantly between the groups. Conclusions: Dietary counseling helps to maintain body weight, maintain dietary intake, and enhance treatment responses in lung cancer patients. Although not all nutritional markers or survival outcomes were affected, these findings highlight the importance of early nutritional interventions.

Two-year follow-up of a brisk walking programme on fitness, perceived health and physical activity engagement in postmenopausal women

Objective: Brisk walking helps postmenopausal women to maintain body weight and fat mass losses as well cardiorespiratory fitness (CRF) and to feel better. However, these long-term benefits have not been fully examined. The aims of this study were to compare the effects of a 2-year follow-up with those of a 4-month walking programme on body composition, resting blood pressure (BP), CRF and perceived health of 248 sedentary postmenopausal women (60 ± 5 years) with overweight-to-moderate obesity (body mass index, BMI, 30 ± 4 kg/m2). Method: From the study-population, 196 women engaged in an outdoor walking programme consisting of three sessions of 45 minutes/week at 60% of their heart rate reserve (initially exercised, IEx, group), and another 52 formed the initial control group (ICo). Ninety-one IEx and 18 ICo women were re-examined 2 years later, for all outcomes. Results: In IEx women, decreased body weight, fat mass and BP versus the increased CRF (.0001 &lt; p &lt; .001) as well as improvements in four on six items of perceived health (.0001 &lt; p &lt; .05) were maintained at follow-up. In ICo women, reduced BP and improved perceived healthy balanced diet were the only benefits at follow-up ( p &lt; .05). Of the 91 IEx women, 70 remained physically active (60 minutes/week), and 46 of them engaged in physical activity more than 150 minutes/week. In ICo women, 16 became physically active (60 minutes/week), while 9 of them reached 150 minutes/week. Conclusion: The regular practice of brisk walking in greenspaces could thus be considered a useful health education strategy for middle-aged women.

Incident of Depression In Post Stroke Patients In the Nervous Polyclinic Room of Daya General Hospital Makassar City, South Sulawesi

Stroke is a disorder of blood circulation in the brain, either due to ischemic (non-hemorrhagic stroke) or hemorrhagic (hemorrhagic stroke), which causes a lack of blood supply to the brain. Depression is an emotional disorder experienced by a person that can make him feel sad and helpless. The prevalence of stroke in Indonesia is 12.1 ‰, the highest in the province of South Sulawesi (17.9‰) and the lowest in the provinces of West Papua, Lampung and Jambi (5.3‰). The aim of this study was to determine the description of the incidence of depression in post-stroke patients in the Neurology Clinic at Makassar Hospital. The type of research used in this research is descriptive survey research. The instrument in this research uses a questionnaire. The sample in this study was 38 post-stroke patients taken using accidental sampling technique. The results of this study showed that of the 38 respondents (100.0%), 33 respondents (86.8%) were Ischemic (Non-Hemorrhagic Stroke) and 5 respondents (13.2%) were Hemorrhagic (Hemorrhagic Stroke). For the incidence of depression, from 38 respondents (100.0 %), the highest incidence of depression was mild depression, 9 respondents (23.7%) and the lowest was 6 respondents who were not depressed (15.8%). The conclusion of this research is that the incidence of depression in post-stroke patients at the Makassar Hospital Neurology Clinic is that the majority experienced non-hemorrhagic strokes and the majority had mild depression. Patients are advised to reduce or prevent atherosclerosis and Obstructive Sleep Apnea while sleeping by maintaining a lifestyle such as exercising frequently, maintaining body weight, and having regular health check-ups at health facilities. This is useful for avoiding ischemic strokes or Non-Hemorrhagic Strokes. and it is recommended that respondents always view the stressors they experience positively.

Malnutrition alters protein expression of KNDy neuropeptides in the arcuate nucleus of mature ewes.

The neuropeptides kisspeptin, neurokinin B, and dynorphin A are imperative for the pulsatile secretion of gonadotropin-releasing hormone and luteinizing hormone to ultimately regulate reproductive cyclicity. A population of neurons co-expressing these neuropeptides, KNDy neurons, within the arcuate nucleus of the hypothalamus (ARC) are positioned to integrate energy status from afferent neuronal and glial cells. We hypothesized that KNDy-expressing neurons in the ARC of mature ewes are influenced by energy balance. To test this hypothesis, ovary-intact, mature ewes were fed to lose, maintain, or gain body weight and hypothalamic tissue harvested during the luteal phase of the estrous cycle. Fluorescent, multiplex immunohistochemistry with direct antibody conjugation was employed to identify and quantify neurons expressing a single neuropeptide, as well as for the first time report co-expression of kisspeptin, neurokinin B, and dynorphin A protein in the ARC. Previous reports using this population of ewes demonstrated that concentrations of insulin and leptin differed between ewes fed to achieve different body weights and that ewes fed to gain body weight had increased concentrations of progesterone. Moreover, within this population of ewes tanycyte density and cellular penetration into the ARC was increased in ewes fed to gain body weight. Within the current report we have revealed that the number of neurons in the ARC expressing kisspeptin, neurokinin B, and dynorphin A protein was increased in ewes fed to gain body weight. Moreover, the number of KNDy neurons in the ARC expressing all three neuropeptides within a single neuron was decreased in ewes fed to lose body weight and increased in ewes fed to gain body weight when compared to ewes fed to maintain body weight. The cumulative findings of this experimental model suggest that expression of kisspeptin, neurokinin B, and dynorphin A protein in the ARC during the luteal phase of the estrous cycle are influenced by energy balance-induced alterations in circulating concentrations of progesterone that drive changes in morphology and density of tanycytes to ultimately regulate central perception of global energy status. Moreover, these results demonstrate that changes in KNDy neurons within the ARC occur as an adaptation to energy balance, potentially regulated divergently by metabolic milieu via proopiomelanocortin afferents.

The Role of Microbiota on the Incidence of Obesity

Obesity is predicted to become a global public health problem, especially in developing countries. Obesity is characterized by a body mass index (BMI) of 30 or more, which is calculated by dividing a person's weight by the square of their height (in kilograms per square meter). The incidence of obesity by age increased from 4.6% in 1980 to 14.0% in 2019. According to the World Health Organization (WHO), around 2 billion adults are classified as overweight, while another 650 million people are categorized as obese. Based on a national survey, the obesity rate in Indonesia is 23.1%, while in South Sulawesi province it is 31.6% (Riskesdas, 2018). This can alter the gut microbiota structurally and functionally, and the gut microbiota can also modulate nutritional status. A certain abundance and diversity of bacteria may facilitate energy storage and metabolic pathways that lead to obesity. Dietary interventions with probiotics, prebiotics, or synbiotics may be effective in counteracting the disturbances observed in the gut microbiota during obesity or unbalanced diets, as they may be able to reduce and maintain body weight. Intestinal anaerobic bacteria, including Firmicute and bacteroids, can hydrolyze carbohydrates that cannot be digested by the intestine, obtaining short chain fatty acids (SCFA) including acetate, propionate and butyrate, which have an impact on human health. Therefore, anaerobic bacteria can inhibit obesity.

Alternative isoform expression of key thermogenic genes in human beige adipocytes.

The beneficial effect of thermogenic adipocytes in maintaining body weight and protecting against metabolic disorders has raised interest in understanding the regulatory mechanisms defining white and beige adipocyte identity. Although alternative splicing has been shown to propagate adipose browning signals in mice, this has yet to be thoroughly investigated in human adipocytes. We performed parallel white and beige adipogenic differentiation using primary adipose stem cells from 6 unrelated healthy subjects and assessed differential gene and isoform expression in mature adipocytes by RNA sequencing. We find 777 exon junctions with robust differential usage between white and beige adipocytes in all 6 subjects, mapping to 562 genes. Importantly, only 10% of these differentially spliced genes are also differentially expressed, indicating that alternative splicing constitutes an additional layer of gene expression regulation during beige adipocyte differentiation. Functional classification of alternative isoforms points to a gain of function for key thermogenic transcription factors such as PPARG and CITED1, and enzymes such as PEMT, or LPIN1. We find that a large majority of the splice variants arise from differential TSS usage, with beige-specific TSSs being enriched for PPARγ and MED1 binding compared to white-specific TSSs. Finally, we validate beige specific isoform expression at the protein level for two thermogenic regulators, PPARγ and PEMT. These results suggest that differential isoform expression through alternative TSS usage is an important regulatory mechanism for human adipocyte thermogenic specification.
