Influence of Alkaline Reduced Water Supplementation on Glucose and Lipid Metabolism in Non-Diabetic and Diabetic Rats

Background: With the global increase in metabolic disorders, identifying effective dietary strategies is crucial for enhancing health outcomes. While various health advantages of alkaline reduced water (ARW) have been documented, its specific impacts on glucose and lipid metabolism in both healthy and diabetic conditions are still not well understood. Methods: This study investigates how ARW affects carbohydrate and lipid metabolism in male Wistar rats, which were induced to develop glucose metabolism disorders through subcutaneous injections of nicotinamide and streptozotocin (STZ). The rats were allocated into four groups: one group received distilled water, another ARW, with similar arrangements for both non-diabetic and diabetic rats. Throughout the six-week experiment, the rats had unrestricted access to food and water. At the end of the study, blood and tissue samples were collected post-euthanasia for further analysis. Results: Non-diabetic rats consuming ARW experienced significant decreases in plasma glucose, triglycerides, cholesterol, insulin, leptin, and TBARS levels, along with reduced activities of hepatic hexokinase and intestinal sucrase. Meanwhile, there were increases in hepatic antioxidant enzyme activities, such as glutathione peroxidase and glucose-6-phosphate dehydrogenase, although glutathione levels decreased. In diabetic rats, ARW supplementation notably reduced plasma glucose and the glucose area under the curve, lowered hepatic glucose-6-phosphatase and intestinal disaccharidase activities, and raised hepatic GSH levels. Conclusions: These findings suggest that ARW supplementation significantly enhances glucose and lipid metabolism and boosts antioxidant activity in both non-diabetic and diabetic rats, indicating its potential as a therapeutic aid for managing metabolic disorders.

Antidiabetic Activity Test of Fe(III) Complex Compound with Arginine Ligand in Male Mice (Mus Musculus L.)

Diabetes mellitus is characterized by high blood sugar levels in the body. Treatment for type 1 diabetes mellitus is with insulin injections while treatment for type 2 diabetes mellitus generally uses oral medication. Currently, people are looking for diabetes drugs made from complex compounds using metals. The development of research and utilization of Fe(III) complex compounds is still limited, thus, in this study the synthesis of Fe(III) complex compounds with arginine ligands was carried out. The results of the research obtained a complex compound of Fe(III)-arginine with 96%, in the form of a brown gel with a sample weight of 0.5601 g. Characterization using a UV-Vis spectrophotometer showed absorption at a wavelength of 203 nm which indicated the absorption of the Fe(III)-arginine complex. The results of FTIR analysis showed a typical absorption of Fe–O and Fe–N bonds at a wavelength of 500–600 nm. The results of the calculation of the mice's body weight decreased when induced by alloxan. After 3 and 4 weeks, the mice's body weight returned to stability. The highest decrease in glucose levels was in dose 2, namely 100 μg/kg bw with a decrease in %GL of 66.72%. The results of this study show that the complex compound Fe(III) arginine can reduce blood glucose levels in mice.

Edaravone Ameliorate Inflammation in Vitamin D3 and High Fat Diet Induced Atherosclerosis in Rat via Alteration of Inflammatory Pathway and Gut Microbiota.

Cardiovascular disease refers to a group of conditions that affect the heart and blood vessels, including coronary artery disease, heart failure, and stroke, among others. Edaravone (ED) inhibits oxidative stress and free radical damage, which are thought to contribute to the progression of various diseases. Thus, the purpose of the study is to examine the cardioprotective effect of ED against vitamin D3 and high fat-induced atherosclerosis in rats. In this study, Sprague Dawley (SD) rats were utilized. The rats were separated into several groups and fed a high-fat diet along with vitamin D3 to induce atherosclerosis. Various doses of ED were orally administered to the animals for 30 days. The administration of Edaravone effectively reduced the elevated body weight, as well as the excessive water and food consumption. The treated groups exhibited a decrease in glucose level, leptin, and apolipoprotein-B. Administration of ED also modified the cholesterol parameters, coronary artery index, atherogenic index, and antioxidant parameters. It also reduced the elevated heart rate, systolic blood pressure (BP), mean BP, and diastolic BP. The group treated with ED exhibited a decrease in the level of inflammatory cytokines. The ED significantly (p < 0.001) reduced the levels of MMP-2, MMP-3, and MMP-9. Furthermore, it induced significant (p < 0.001) adjustments in the abundance of Firmicutes, Bacteroidetes, Proteobacteria, Verrucomicrobia, and F/B ratio. Edaravone exhibited the cardio protection against HFD induced atherosclerosis in rats via alteration of gut microbiota.

Impact of Cryptosporidium parvum infection on glucose transport and metabolism in calves: Physiological and molecular insight

The present study aimed to assess the impact of Cryptosporidium parvum infection on physiological parameters and glucose metabolism in calves. To achieve this goal, a study was conducted in Moscow, Russia, from 2022 to 2023, involving 20 calves, of which 10 were infected with C. parvum and 10 comprised the control group. Comprehensive methods were employed, including body weight measurement, fecal analysis, histopathological examinations, blood analysis, Using chamber experiments, and molecular analyses. The results of the study revealed a statistically significant decrease in body weight in the infected calf group (P < 0.052) and noticeable changes in fecal consistency changes were noticed on the 4th-day post-infection (P < 0.01). Histopathological examination identified acute catarrhal enteritis and villus atrophy in the small intestine of infected calves. Blood analysis demonstrated a statistically significant decrease in glucose levels in infected calves on the 6th and 7th days post-infection (P < 0.05). However, the results of the Ussing chamber experiments and studies of glucose metabolism genes did not reveal statistically significant differences between the groups. The findings suggest the potential applicability of monitoring body weight, fecal consistency, and glucose levels in the diagnosis and control of cryptosporidiosis in cattle, which could lead to a reduction in economic losses in agriculture.

Effect of Trichosanthes cucumerina Methanol Extract on CRP and Fibrinogen Levels in Diabetic Ulcer Rat Models

Diabetic ulcers can be fatal for people with long-term diabetes. This is caused by the spread of diabetic ulcers and inadequate care for the wound, which can induce an infection and even death. This study aims to determine inflammatory markers, specifically fibrinogen and C-Reactive Protein (CRP), as indicators of healing, particularly in a rat model of diabetic ulcers treated with Trichosanthes cucumerina methanol extract. The methods used were making extracts, measuring blood glucose levels, measuring CRP, and measuring fibrinogen levels in 25 male Wistar rats. Based on the results of glucose and fibrinogen examinations in all groups before treatment and after treatment, it showed a decrease in glucose and fibrinogen levels. Meanwhile, the results of CRP examinations, before and after treatment did not show any differences. The results of statistical analysis showed that there was a significant difference of p&lt;0.05 in pre and post glucose, as well as pre and post fibrinogen.The extract that reduced fibrinogen levels the most was group 3 with 500 mg/KgBW. Meanwhile, CRP levels before and after treatment did not show a decrease.

Buspirone administration: Influence on growth, spawning, immune response, and stress in female goldfish (Carassius auratus)

The current study evaluated the impact of buspirone supplementation on the growth, physiology, stress response, spawning, and immunity in female goldfish (Carassius auratus). For this purpose, buspirone was dissolved in absolute methanol and sprayed onto the feed to create four experimental groups: B0 (control), B25 (25 mg kg−1), B50 (50 mg kg−1), and B100 (100 mg kg−1). Fish were fed their respective diets for 56 days and subjected to stress using the air exposure method at the end of the experiment. Growth performance analysis revealed that fish in the B100 group exhibited significantly higher final weight, weight gain, specific growth rate, and average daily gain than the other groups (P < 0.05). Plasma stress response indicated that cortisol levels were significantly lower in the B100 group after stress exposure, accompanied by a simultaneous decrease in glucose levels. The mucus stress response also showed lower cortisol and glucose levels in the B100 group compared to the other groups. Immunological analysis revealed significant increases in total protein, albumin, complement C3 and C4, and immunoglobulin M concentrations in both plasma and mucus of the B100 group (P < 0.05). Reproductive performance showed a notable enhancement in the number of eggs, fertilization rate, hatching rate, and survival rate in the B100 group compared to other groups (P < 0.05). Buspirone at higher concentrations, positively impacted various physiological aspects of goldfish, including growth, stress, immune activity, and reproductive performance. The significant improvements observed in growth parameters, cortisol levels, immunological markers, and reproductive outcomes suggest the potential of buspirone supplementation as a beneficial strategy in aquaculture practices.

Acute ketone monoester supplementation in young adults: modulating metabolic and neurocognitive functions across body weights.

This study investigated the acute effects of ketone monoester on metabolic and neurocognitive indicators and underlying metabolism-brain-cognition interactions among young adults of healthy weight (HW) and those with overweight/obesity (OW). Forty participants were divided into two groups: HW (n=20, age 23.80±3.96 years, body mass index (BMI) 21.49±1.80 kg/m2) and OW (n=20, age 22.00±2.13 years, BMI 28.23±3.48 kg/m2). Each participant completed two trials (ketone monoester vs. placebo, 395 mg/kg dose) in a randomized order. Metabolic indicators (blood beta-hydroxybutyrate (BHB) and glucose) and neurocognitive function (causal density via functional near-infrared spectroscopy and cognitive interference via the Stroop task) were measured at baseline, 30 min, and 90 min post-supplementation. A chain mediation model was constructed to test the indirect effects of BHB level on cognitive interference through mediators like blood glucose and causal density. In the linear mixed models, significant effects were observed for trial (β = -0.92, 0.20, -0.04, 25.53) and assessment time (β = 0.50, -0.14, 0.09, -62.88) in BHB, glucose, causal density, and cognitive interference (p<0.05), but not for group factors. Compared to OW, the effects of ketone monoester on prefrontal connectomes were more enduring in the HW (p<0.05). Elevated BHB level improved cognitive function through decreasing glucose level and increasing causal density, with an estimate of -0.63. Acute ketone monoester supplementation elevated levels of blood BHB and prefrontal connectomes and decreased levels of glucose and cognitive interference, regardless of weight status. Elevated blood BHB enhanced cognitive function through multi-tiered neurometabolic pathways. Clinical trial registration: ClinicalTrials.gov (ID: NCT06368297).

Sex dimorphism and hormesis response to polystyrene microplastic exposure in kinematics and metabolism of Drosophila model based on deep learning

The emergence of microplastics (MPs) has become a significant focus of environmental pollution, prompting widespread concern regarding its potential toxicity and impact on the environment and organisms. Recent research indicates notable alterations in insect metabolism and behavioral patterns under the influence of MPs. In this study, the fruit fly (Drosophila melanogaster) was employed as a model organism to investigate the effects of polystyrene microplastics (PS-MPs) on insect behavior, with behavioral parameters used to quantify and assess its toxic effects on fruit flies. Five concentrations (0 g/L, 0.1 g/L, 1 g/L, 10 g/L, 20 g/L) of 5 μm PS-MPs were introduced into the environment, and fruit flies were exposed for 20 days, with subsequent recording of their metabolism and locomotion. In the presence of MPs, both male and female fruit flies exhibited decreasing glucose levels, while protein content decreased in male flies, and irregular gait patterns were observed in both genders. Further quantification of gait parameters revealed that male fruit flies experienced reduced velocity, increased stride length, and larger wing beat angles under microplastic exposure, whereas females exhibited pronounced excitatory effects such as increased velocity and wing beat frequency at lower concentrations, which diminished with higher concentrations, indicating a biphasic response and excitatory effects induced by PS-MPs. These findings highlight the significant impact of PS-MPs on fruit fly metabolism and behavioral patterns, raising concerns regarding the use of PS-MPs.

7490 Comparative Clinical Analysis of DPP-4 inhibitors and SGLT2 inhibitors; Switch Study in Real-World Setting

Abstract Disclosure: H. Choe: None. M. Kwak: None. J. Lee: None. Y. Choi: None. E. Hong: None. Objective: Dipeptidyl peptidase-4 inhibitors (DPP-4i) and sodium-glucose cotransporter-2 inhibitors (SGLT2i) represent two distinct pharmacological pathways in the management of type 2 diabetes, both aiming to improve glycemic control without risk of hypoglycemia. Metabolic implications and glycemic control associated with the interchange between SGLT2i and DPP-4i are scarce. This study aimed to evaluate the effect of switching between SGLT2i and DPP4i on various clinical parameters in Korean patients with type 2 diabetes. Methods: We conducted a retrospective cohort study at Hallym University Dongtan Sacred Heart Hospital, using clinical data warehouse. Baseline measurements and follow-up data at 3 months were collected for parameters including hemoglobin A1c (HbA1c), blood pressure, lipid profile, liver enzymes, renal function, and other metabolic markers. Results: Between 2015 and 2023, 104 participants switched from SGLT2 inhibitors to DPP4 inhibitors, while 321 switched in the opposite direction. Initially, those who switched from SGLT2 inhibitors to DPP4 inhibitors presented with lower baseline HbA1c levels (7.22 ± 0.73% versus 7.42 ± 0.76%, P = 0.017) and higher estimated glomerular filtration rates (eGFR) (95.2 ± 23.1 versus 85.9 ± 23.7 mL/min/1.73m², P = 0.001) compared to those who switched from DPP4 inhibitors to SGLT2 inhibitors. At three months of follow-up, the SGLT2 inhibitors to DPP4 inhibitors group exhibited a more significant reduction in HbA1c (adjusted β 0.22, 95% CI 0.03 to 0.40, P = 0.023), especially in patients with reduced eGFR (&amp;lt;60 mL/min/1.73 m²) (β 1.2, 95% CI 0.30 to 2.11, P = 0.013; P for interaction = 0.005). On the other hand, the DPP4 inhibitors to SGLT2 inhibitors group showed a greater decrease in fasting glucose levels (β -9.73, 95% CI -17.6 to -1.86, P = 0.016), along with more pronounced reductions in liver enzymes AST (β -4.15, 95% CI -6.49 to -1.81, P &amp;lt; 0.001) and ALT (β -6.42, 95% CI -9.58 to -3.27, P &amp;lt; 0.001), and a significant increase in hematocrit (β 3.31, 95% CI 2.36 to 4.26, P &amp;lt; 0.001) compared to the initial group. Conclusions: The study concludes that in Korean patients with type 2 diabetes, switching from SGLT2 inhibitors to DPP4 inhibitors is associated with a greater reduction in HbA1c, particularly in those with reduced renal function. Conversely, switching from DPP4 inhibitors to SGLT2 inhibitors results in more substantial improvements in fasting glucose and liver enzyme levels, suggesting differential benefits depending on the direction of the medication switch.

12491 Follow Up Of Glycemic Control In Patients Users Of Sensor Augmented Insulin Pump (sap) After Multi Dairy Injection (mdi) Or Change Of Technology

Abstract Disclosure: A. Medina: None. S. Tabares: None. C. Coronado: None. L. Burgos: None. A. Ely: None. Introduction: Sensor augmented insulin pump (SAP) is considered an efective therapy in type 1 diabetes (T1D) that combines continuous subcutaneous insulin infusion (CSII) with continuous glucose monitoring (CGM). A new metric of glycemic control is the time in range (TIR). More time in the expected range means less severe highs and lows. Objective: To describe glycemic control of a cohort of patients treated with multi-daily injection (MDI) or sensor-augmented insulin pump (SAP) VEO /640G who switched to a new therapy with 640G, 670G and 780G at 3 and 6 months. Methodology: A cohort study was analyzed with patients with T1D receiving SAP therapy in an university hospital. Patients with insulin therapy with MDI or SAP (VEO /640G) prior to SAP (670G /780G) were included and were followed up with glycemic control trough A1c, time in range (TIR), time in hypoglycemia and hyperglycemia, glycemic variability (GV) using continuous glucose monitoring (CGM) for 14 days, at 3 and 6 months after starting a new technology. Results: 40 patients were analyzed from 2022 to 2023, who attended check-ups every 3 months. The median age was 32 y and 65% were male. At baseline data, 40%, 22.5%, 37.5% were on MDI, VEO and 640G respectively, before changing therapy to 670G or 780G. The TIR increased by 97.6% of the patients and 75% reached the TIR (&amp;gt;70% between 70 and 180 mg/dl of glucose).Hypoglycemia decreased in 75% of patients, and of 27 patients in hyperglycemia, only 3, did not decrease glucose levels due to: lack of follow-up, sensor failure and misuse of the pump. In this cohort were included 12 patients in special conditions. The average initial GV was 37,2%, the normal being &amp;lt;36%, with an improvement at 3 and 6 months of 32,8 and 32,9%, respectively.The mean basal A1c was 7,32% . A1c decreased to 6,8 and 6,9% at 3 and 6 months after new therapy. Discusion: Regardless of the basal therapy (MDI, SAP), an improvement in TIR and A1c as measures of glycemic control is observed, as well as a decrease in the time in hypo and hyperglycemia and GV. The few patients who did not experience improvement had poor pump management, inappropriate carbohydrate counting, or poor adherence at checkups. Conclusion: SAP is an effective therapy in patients with (T1D) to reach metabolic goals, without increasing the rate of hypoglycemia. The most recent technologies in insulin pumps demonstrate better glycemic control. Presentation: 6/1/2024

Effect of ketone monoester supplementation on elite operators' mountaineering training.

Special Operations Forces (SOF) often conduct operations in physiologically stressful environments such as severe heat, cold, or hypoxia, which can induce decreases in a variety of cognitive abilities. Given the promising empirical demonstration of the efficacy of exogenous ketone monoester (KME) supplementation in attenuating cognitive performance decrease during hypoxia at rest in a laboratory setting, we conducted a real-world, field experiment examining KME's efficacy during high-altitude mountaineering, an austere environment in which US SOF have conducted increasing numbers of operations over the past two decades. Specifically, 34 students and cadre at the US Army 10th Special Forces Group Special Operations Advanced Mountaineering School (SOAMS) participated in a randomized, double-blind, placebo (PLA)-controlled crossover trial (KME vs. PLA) over 2days of tactical mountain operations training. The participants ascended from 7,500 ft in altitude (basecamp) to 12,460 ft on 1 day and 13,627 ft the other day (in randomized order), while performing various training activities inducing high physical and cognitive loads over 8-12h, and consumed six doses of KME or PLA 2-3h apart throughout each training day. While KME increased blood ketone levels and decreased glucose levels, there were no clear indications that the elevated ketone level enhanced physical or cognitive performance. KME also produced a greater incidence of heartburn, nausea, and vomiting. In these elite operators, high-altitude mountaineering had a limited impact on cognitive performance, and KME supplementation did not demonstrate any benefit.

Evaluating the Preferences and Willingness-to-Pay for Oral Antidiabetic Drugs Among Patients with Type 2 Diabetes Mellitus in China: A Discrete Choice Experiment.

To quantify the preferences for an oral antidiabetic drug (OAD) among patients with type 2 diabetes mellitus (T2DM) in China. A discrete choice experiment (DCE) with hypothetical OAD profiles was performed among patients with T2DM recruited from both online and offline sources. Each patient completed 12 DCE choice tasks. The attributes, elicited through mixed methods, include blood glucose level decrease, blood glucose level stability, frequency of medication, gastrointestinal side effects, dose adjustment and out-of-pocket expense. The conditional logit regression model was used to analyze the data. Patients' willingness-to-pay (WTP) was also calculated. Subgroup analyses based on patient characteristics were also conducted. A total of 741 respondents were included in the analysis sample, covering 456 respondents online and 285 offline. The result showed that all attributes and levels were statistically significant, except one level "dose adjustment required for patients with hepatic or renal insufficiency" in the attribute of dose adjustment. WTP results showed that patients were willing to pay 12.06 and 23.20 yuan, respectively to reduce the frequency of medication from "once per day" and "three times per day" to "once every 2 weeks", respectively. Subgroup analyses showed that the frequency of medication (once versus two to three times per day) had the largest impact and influenced most coefficient estimates. The results suggest that Chinese patients with T2DM prioritized better efficacy, less frequency of medication, lower gastrointestinal side effects, no dose adjustment required for patients with hepatic or renal insufficiency, and less out-of-pocket expense of OAD treatment.

AMELIORATION OF LIVER AND KIDNEY FUNCTION PARAMETERS IN ALLOXAN-INDUCED DIABETIC RATS TREATED WITH 3-[2-(1,5-Dimethyl-3-oxo-2-Phenyl-2,3-Dihydro- 1H-Pyrazol-4-yl) Hydrazinylidene]-1-Phenylbutanedione, and its Ni(II) Complex.

This hydrazone: 3-[2-(1,5-Dimethyl-3-oxo-2-Phenyl-2,3-Dihydro-1H-Pyrazol-4-yl) Hydrazinylidene]-1-Phenylbutanedione (HL), and its Ni (II) Complex ([Ni(HL)2]Cl2) have been reported to possess hypoglycaemic property but the effects of their use on kidney and liver functions in diabetic animals have not been investigated. The study investigated some biochemical parameters in the liver and kidney of alloxan-induced diabetic rats treated with these hydrazone compounds. Diabetes was induced by a single intraperitoneal dose of alloxan (150 mg/kg). Data showed that these compounds induced a significant decrease in serum glucose levels in the diabetic rats. Diabetic rats were administered orally with compounds for fourteen days after which some biochemical indices in the serum, liver and kidney were measured and compared with the control. Serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, total protein and creatinine of untreated diabetic group was significantly elevated when compared with the normal control group. The ALP, AST concentrations of diabetic rats treated with low and high doses of HL was observed to be non-significantly (p &gt; 0.05) higher compared with rats in the normal control group A. A significantly (p &lt; 0.05) decrease in the ALT, AST and ALP concentrations of diabetic rats treated with 200 and 400 mg/kg b.w. of HL and [Ni(HL)2]Cl2 were observed when compared with untreated rats in group B. These results suggest that administration of these compounds to diabetic rats did not have any adverse effect on the liver and kidney functions in rats showing that the compounds are not toxic to man.

Postprandial glycemic response to isocaloric protein load in men with different types of fat distribution

Aim of the study was to quantify postprandial glucose levels in response to isocaloric protein load at main meals in men with different types of fat distribution. Material and methods. The study enrolled men aged 25 to 65 years. Group 1 (n = 17) consisted of obese men with subcutaneous fat distribution (SFD) type while group 2 (n = 16) was represented by obese men with abdominal type of fat distribution (AFD). Group 3 (comparators) consisted of 10 men with normal body weight (NBW). Glycemic response to standard isocaloric protein load was assessed by the results of glucose levels within 3 hours starting 5 minutes after end of food consumption on different days and mealtime. Standard protein lunch was introduced during the second day while standard protein dinner and breakfast were performed at the third and fourth days respectively. Results. It was found that protein intake leads to neither pronounced postprandial glycemic fluctuations nor decrease in glucose levels by the end of the 3rd hour of the test. Accordingly, it also doesn’t provoke hunger, unlike carbohydrate intake does. In men with NBW a more pronounced increase in glucose level after protein meal was found, both relative to the baseline levels and comparing with men from SFD and AFD groups. In NBW group at lunchtime and especially in the evening a double-humped glycemic curve was noted. Glycemic variability in men with different types of fat distribution was characterized by the fact that glycemic increment was more pronounced in men with AFD than in men with SFD whose glycemic curve was almost flat after all meals. Conclusions. Protein intake in men with NBW and different types of fat distribution does not lead to significant changes in postprandial glucose levels. Glycemic fluctuations don’t exceed 1 mmol/L within a 3-hour period after consuming of isocaloric breakfast, lunch or dinner. Protein intake results in greater postprandial glucose levels in men with AFD than in SFD men.

The role of microglia in neuronal and cognitive function during high altitude acclimatization

Due to their interactions with the neurovasculature, microglia are implicated in maladaptive responses to hypobaric hypoxia at high altitude (HA). To explore these interactions at HA, pharmacological depletion of microglia with the colony-stimulating factor-1 receptor inhibitor, PLX5622, was employed in male C57BL/6J mice maintained at HA or sea level (SL) for 3-weeks, followed by assessment of ex-vivo hippocampal long-term potentiation (LTP), fear memory recall and microglial dynamics/physiology. Our findings revealed that microglia depletion decreased LTP and reduced glucose levels by 25% at SL but did not affect fear memory recall. At HA, the absence of microglia did not significantly alter HA associated deficits in fear memory or HA mediated decreases in peripheral glucose levels. In regard to microglial dynamics in the cortex, HA enhanced microglial surveillance activity, ablation of microglia resulted in increased chemotactic responses and decreased microglia tip proliferation during ball formation. In contrast, vessel ablation increased cortical microglia tip path tortuosity. In the hippocampus, changes in microglial dynamics were only observed in response to vessel ablation following HA. As the hippocampus is critical for learning and memory, poor hippocampal microglial context-dependent adaptation may be responsible for some of the enduring neurological deficits associated with HA.

Renal Protective Effect of Boeravinone B against Diabetic Nephropathy Rats via Inhibition of The Inflammatory and JAK2/STAT3 Signalling Pathway.

Chronic inflammation is a common feature in diabetes, especially when blood sugar levels are poorly controlled. This chronic low-grade inflammation can affect various organs, including the kidneys. Podocyte damage play a key role in the development of diabetic nephropathy (DN). The aim of the study was to evaluate the nephroprotective effect of Boeravinone B (BB) against streptozotocin (STZ) induced DN in rats and explore the underlying mechanism. In this experimental study, the rats received intraperitoneal injections of STZ (60 mg/kg) to induce DN. Various doses of BB (2.5, 5, and 7.5 mg/kg) were administered orally. Glucose levels, body weights, and organ weights (hepatic and renal) were assessed. Renal, histomorphological, antioxidant, hepatic, and cytokine levels were determined, as were the mRNA expression levels of JAK2 and STAT3. At end of the experimental study, the rats were sacrificed and their renal tissues were removed for histopathological assessment. BB treatment decreased glucose levels and increased body weights. This treatment suppressed hepatic weights, increased renal tissue weights, and also decreased renal parameters like uric acid, urea, bilirubin, creatinine (Cr) and, albumin. There was a decrease (P<0.001) in histomorphological parameters such as kidney hypertrophy index (KHI), mean glomerular volume (MGV), foot process fusion ratio (FPFR), and glomerular basement membrane thickness (GBMT) after treatment with BB. In addition, this treatment improved the levels of renal podocin, renal CD2- associated protein (CD2AP) and suppressed hepatic parameter levels. BB treatment (P<0.001) altered antioxidant parameters and cytokine levels, and suppressed mRNA expressions of JAK2, STAT3, RAGE, KIM-1, NAGL, and S100A8. Administration of BB showed renal protective effects against STZ-induced DN in rats via the reduction of oxidative stress and inflammatory reactions.

Exploring the combined therapeutic efficacy of bexarotene and icariin in type 2 diabetic rats.

The aim of this study was to determine the single and combined antidiabetic activity and side effects of the retinoid X receptor agonist bexarotene and the thioredoxin-interacting protein inhibitor and peroxisome proliferator-activated receptor γ and AMP-activated protein kinase activator icariin. The rats were grouped as healthy (control), diabetes, diabetes + bexarotene (20 mg/kg), diabetes + icariin (60 mg/kg), diabetes + bexarotene (10 mg/kg) + icariin (30 mg/kg) low-dose combination and diabetes + bexarotene (20 mg/kg) + icariin (60 mg/kg) high-dose combination groups. Icariin treatment led to a significant reduction in glucose levels compared with the diabetes control group, a remarkable outcome observed 45 days after the initial application. HbA1c levels of the icariin and low-dose combination treatment groups were significantly lower than in the diabetes group. Notably, icariin treatment also significantly elevated HOMA-β levels, which is indicative of improved β-cell function. Icariin significantly decreased glucose levels at 30 and 120 min in the oral glucose tolerance test. Moreover, it ameliorated hepatocyte degeneration, hepatic cord dissociation, congestion, mononuclear cell infiltration in the liver, and degeneration in the pancreas. Icariin treatment exhibited robust antidiabetic effects with fewer side effects than other treatment options in this study. In future studies, long-term and varying doses of icariin will contribute to the development of novel antidiabetic drugs.

Inside the Brain: Cerebrospinal Fluid Insights in Meningitis.

Background Our study focused on meningitis, an infection that can spread through the bloodstream as a primary or secondary infection from other body parts, such as sinuses, ears, and lungs. It can affect patients who have experienced trauma or surgery, as well as those with congenital defects like spina bifida. Specifically, we examined bacterial, viral, and tuberculous meningitis (TBM) cases. The primary method for confirming the diagnosis of these types of meningitis is to analyze the cerebrospinal fluid (CSF). Early diagnosis can utilize cytological and biochemical parameters. Our objective is to determine CSF's cytological and biochemical profile in patients with these specific types of meningitis. Methods A study was carried out at the central pathology lab from October 24, 2017, to April 24, 2018.CSF samples from suspected meningitis patients were examined for various parameters, including hematological, biochemical, microbiological, and cytomorphological aspects and specific tests for bacterial, fungal, and TBM. The study focused on patients aged 16 and above, excluding those under 16, non-compliant patients, and individuals with specific health conditions. Data were analyzed using IBM SPSS Statistics for Windows, Version 20 (Released 2011; IBM Corp., Armonk, New York, United States), and the results were presented through the use of mean, standard deviation, and percentages. Statistical tests were utilized to compare categorical variables and mean, with a significance level of p<0.05. Results We included a total of 156 cases, with the mean age of presentation being 56.628 years. The male-to-female ratio was 1.0526:1. Of the patients, 81 (52.1%) had been diagnosed with TBM, had elevated adenosine deaminase (ADA) levels of 48.8733±37.43740 IU/L, and CSF lymphocytosis (99%). Additionally, cases of bacterial meningitis showed markedly raised mean total leukocyte count (TLC) of 2085.50±445.47727 cells/mm3 and mean CSF protein levels of 349.45±113.73105 mg/dL. The study found a significant increase in protein levels and a decrease in glucose levels in the CSF of TBM and bacterial meningitis patients compared to those with other causes of meningitis (p<0.001). Guillain-Barre syndrome (GBS)and multiple sclerosis (MS) patients had TLC and ADA within normal limits.CSF ADA level greater than 6 IU/L showed a sensitivity of 97.53% and a specificity of 96.0%, making it the most specific test. A protein level in the CSF greater than 45 mg/dL demonstrated a sensitivity of 98.78% and a specificity of 24.32%, indicating it is sensitive but less specific in diagnosing TBM. Lymphocytic predominance, defined as TLCof more than 5 cells/mm3 with at least 50% of the cells being lymphocytes in the CSF of TBM patients, showed a sensitivity of 97.53% and a specificity of 6.67%. CSF glucose had a sensitivity of 38.27%, making it the least reliable indicator for diagnosing meningitis. Conclusion The CSF analysis is the primary diagnostic method for detecting meningitis. Its cost-effectiveness is a key factor, especially for patients from lower socioeconomic backgrounds in government medical colleges in India, where access to expensive diagnostic tests is limited. The efficiency of CSF analysis for early diagnosing different types of meningitis aids in management, helping to prevent complications and fatal outcomes.

Effect of sodium glucose Co-transporter 2 inhibitor use on anthropometric measurements and blood glucose in obese and non-obese type 2 diabetic patients

Obesity and type 2 diabetes mellitus are closely associated with each other and require careful management. This study aimed to assess the impact of sodium-glucose co-transporter 2 (SGLT2) inhibitors on glycemic control and body composition in diabetic patients, stratified by obesity status. We enrolled patients diagnosed with type 2 diabetes mellitus, categorized as obese (BMI≥30) or non-obese (BMI<30), from our outpatient clinic. SGLT2 inhibitor therapy was added to their existing treatment regimen without altering dietary habits or exercise routines. Anthropometric measurements and laboratory parameters were compared between baseline and the third month of treatment. The study included 40 participants, evenly split between obese and non-obese groups. At the third-month follow-up, significant reductions were observed in BMI, weight, waist and hip circumference, and body fat percentage across both groups (p<0.001). Conversely, muscle mass percentage significantly increased (p<0.001). Additionally, there were statistically significant decreases in HbA1c, glucose, CRP, ALT, LDL, and total cholesterol levels from baseline to the third month of treatment (p<0.001 for HbA1c and glucose; p=0.009, p=0.022, p=0.003, and p=0.021, respectively, for CRP, ALT, LDL, and total cholesterol). The findings of the present study suggest that SGLT2 inhibitors may offer substantial benefits, particularly in the management of obesity-related type 2 diabetes.

Dietary Pectin from Premna microphylla Turcz Leaves Prevents Obesity by Regulating Gut Microbiota and Lipid Metabolism in Mice Fed High-Fat Diet.

The present study was designed to investigate the protective effects of pectin extracted from Premna microphylla Turcz leaves (PTP) against high-fat-diet (HFD)-induced lipid metabolism disorders and gut microbiota dysbiosis in obese mice. PTP was made using the acid extraction method, and it was found to be an acidic pectin that had relative mole percentages of 32.1%, 29.2%, and 26.2% for galacturonic acid, arabinose, and galactose, respectively. The administration of PTP in C57BL/6J mice inhibited the HFD-induced abnormal weight gain, visceral obesity, and dyslipidemia, and also improved insulin sensitivity, as revealed by the improved insulin tolerance and the decreased glucose levels during an insulin sensitivity test. These effects were linked to increased energy expenditure, as demonstrated by the upregulation of thermogenesis-related protein UCP1 expression in the brown adipose tissue (BAT) of PTP-treated mice. 16S rRNA gene sequencing revealed that PTP dramatically improved the HFD-induced gut dysbiosis by lowering the ratio of Firmicutes to Bacteroidetes and the quantity of potentially harmful bacteria. These findings may provide a theoretical basis for us to understand the functions and usages of PTP in alleviating obesity.
