New analogs of the PPAR pan agonist AL29-26 encompassed ligand (S)-7 showing potent activation of PPARα and -γ subtypes as a partial agonist. In vitro experiments and docking studies in the presence of PPAR antagonists were performed to help interpretation of biological data and investigate the main interactions at the binding sites. Further in vitro experiments showed that (S)-7 induced anti-steatotic effects and enhancement of the glucose uptake.

Fractions were isolated from the leaves extract of and subjected to scrutiny for their prospective anti-obesity properties. An array of preliminar phytochemical, antioxidant, and enzyme inhibition assays were executed, which discerned fractions F1 and F2 as the most effective fractions. These fractions were subsequently studied through experiments, affirming that F2 as the most potent fraction.

The antiobesity potential of bioactive fractions derived from was approached using a combination of in vitro, in silico and in-vivo studies. The study was analyzed to validate and select the potent bioactive fractions of leaves extract through in vitro and in vivo activities targeting obesity. The phytochemical properties of the bioactive fractions were investigated utilizing total flavonoid, total phenolic and total steroidal content.

In the present study, we developed and validated a rapid, specific, sensitive, and reproducible liquid chromatography-electrospray ionization tandem mass spectrometry method for quantifying quercetin (QT) in rabbit plasma using hydrochlorothiazide as the internal standard. Animals were orally administered with optimized QT-loaded nanoemulsion (QTNE) and QT suspension (QTS), equivalent to 30 mg/kg, to the test and control group, respectively. The blood samples were collected at pre-determined time points up to 48 h.

Article Synopsis
  • - A new series of derivatives of the PPARα/γ dual agonist LT175 was developed that effectively activates PPARα as a full agonist and PPARγ as a partial agonist.
  • - In vivo tests on diabetic mice showed that this compound reduced blood glucose and lipid levels without harming vital organs like bone, kidney, or liver.
  • - The compound also slightly inhibited the mitochondrial pyruvate carrier, showcasing a new mechanism for controlling blood sugar levels, making it a potential candidate for treating dyslipidemic type 2 diabetes.

This article shows the adequacy of the custom-built optical imaging system in the advancement investigation of obese mice. Obesity is defined as increased adipose/fatty mass resulting from a chronic imbalance between energy intake and expenditure. The in vivo investigation was performed for the tissue characterization of obese mice utilizing swept-source optical coherence tomography (SSOCT) for in situ examination and histology of delicate tissues in mice skin.

Obesity is a term that has recently been referred to describe a condition in which a person has become a diseased vessel. Obesity's internal pathology is too mysterious as it has a close resemblance with fatal diseases pathology. Obesity and coronavirus disease 2019 (COVID-19) are simultaneous epidemics declared by many organizations after observing their rampage in the recent world.

Insulin resistance is a major pathophysiological feature in the development of type 2 diabetes (T2DM). Ferulic acid is known for attenuating the insulin resistance and reducing the blood glucose in T2DM rats. In this work, we designed and synthesized a library of new ferulic acid amides (FAA), which could be considered as ring opening derivatives of the antidiabetic PPARγ agonists Thiazolidinediones (TZDs).

Peroxisome proliferator-activated receptor γ (PPARγ) has received significant attention as a key regulator of glucose and lipid homeostasis. In this study, we synthesized and tested a library of novel 5-benzylidene-thiazolidin-2,4-dione (BTZD) derivatives bearing a substituent on nitrogen of TZD nucleus (compounds 1a-1k, 2i-10i, 3a, 6a, and 8a-10a). Three compounds (1a, 1i, and 3a) exhibited selectivity towards PPARγ and were found to be weak to moderate partial agonists.

Mirtazapine is an often used antidepressant drug; however insufficient information is available regarding its safety during pregnancy. Therefore, this work was initiated to study the effect of prenatal exposure of mirtazapine on postnatal developments of rats. The study was conducted on pregnant rats to observe the safety profile of mirtazapine in comparison to control.

In recent years, there has been a tremendous increase in the understanding of stem cell biology. Stem cells have clonogenic and self-renewing capabilities, and under certain conditions, can differentiate into multiple lineages of mature cells. Recent studies have shown that adult stem cells can be isolated from a wide variety of tissues, including bone marrow, peripheral blood, muscle, and adipose tissue.

Aim Of The Study: To systematically investigate the anticonvulsant activity of methanol extract of Benkara malabarica roots and to provide a biochemical basis elucidating its mode of action.

Methods: The median lethal dose (LD(50)) of Benkara malabarica extract was determined. The anticonvulsant activity of the extract was assessed in strychnine-induced and isoniazide-induced convulsion models; phenytoin (20mg/kg) and diazepam (1mg/kg) were used as standards, respectively.
