Chimeric antigen receptor (CAR)-T cell therapy represents a breakthrough for the treatment of hematological malignancies. However, to treat solid tumors and certain hematologic cancers, next-generation CAR-T cells require further genetic modifications to overcome some of the current limitations. Improving manufacturing processes to preserve cell health and function of edited T cells is equally critical.

 The keystone design perforator island flap (KDPIF) is unique among local flaps because of its high potential for adaptation. We describe our experience with the use of the keystone flap for the reconstruction of a variety of defects in different regions of the body concerning its versatility, surgical outcomes, complications, postoperative pain, operative time, and esthetic outcomes.  A prospective observational study was conducted at our institute from June 2021 to June 2023 where the use of KDPIFs in resurfacing soft tissue defects of different etiopathogenesis was evaluated and the data were analyzed.

Article Synopsis
  • XIST long noncoding RNA plays a key role in X chromosome inactivation in placental mammals but is present on both X chromosomes in early human embryos without silencing them.
  • XACT lncRNA accumulates alongside XIST on active X chromosomes and may counteract XIST's functions.
  • Research using human embryonic stem cells reveals that XIST modifies chromatin and reduces transcription of X-linked genes, while XACT's absence does not significantly impact XIST’s activity or gene expression, indicating that XIST has a role prior to XCI and highlights a mechanism of temporary X chromosome dosage compensation.

The advent of novel 2D and 3D models for human development, including trophoblast stem cells and blastoids, has expanded opportunities for investigating early developmental events, gradually illuminating the enigmatic realm of human development. While these innovations have ushered in new prospects, it has become essential to establish well-defined benchmarks for the cell sources of these models. We aimed to propose a comprehensive characterization of pluripotent and trophoblastic stem cell models by employing a combination of transcriptomic, proteomic, epigenetic, and metabolic approaches.

This study was planned to develop a simple high-performance thin-layer chromatography method for qualitative and quantitative estimation of 3-acetyl-11-keto-β-boswellic acid (AKBBA), β-boswellic acid (BBA), 3-oxo-tirucallic acid (TCA) and serratol (SRT) with HPTLC-ESI-MS/MS for characterization in Boswellia serrata Roxb. oleo gum resin extract. The method was developed with hexane-ethyl acetate-toluene-chloroform-formic acid as mobile phase.

Background: In India, for the treatment of cold, fever and inflammation, people consume herbal remedies containing (APE) as main ingredient, along with NSAIDs. So the purpose of this study is to investigate the effect of APE and pure andrographolide (AN) on the pharmacokinetic of with aceclofenac (ACF) and celecoxib (CXB) after oral co-administration in wistar rats. After co-administration of APE (equivalent to 20 mg/kg of AN) and AN (20 mg/kg) with ACF (5 mg/kg) and CXB (5 mg/kg) in rats, orally, drug concentrations in plasma were determined using HPLC method.

Ethnopharmacological Relevance: Kalyanaka ghrita (KG) is an Ayurvedic formulation traditionally used in the treatment of Daurbalya (debility) and Smritidaurbalya (impairment of intellectual activities). Clinical studies have reported the effect of KG in the treatment of Manasmandata or Buddhimandyata which is associated with impaired learning, social adjustment and maturation.

Aim Of The Study: The present study aims to standardization of KG and validation of its use in experimental models of neurodegeneration.

Skeletal muscle mass responds rapidly to growth stimuli, precipitating hypertrophies (increased protein synthesis) and hyperplasia (activation of the myogenic program). For ages, muscle degeneration has been attributed to changes in the intracellular myofiber pathways. These pathways are tightly regulated by hormones and lymphokines that ultimately pave the way to decreased anabolism and accelerated protein breakdown.

Introduction A ventral hernia is a common problem in the population. Many patients with umbilical/epigastric hernia often present with diastasis recti (DR) too. Diastasis recti is the thinning of the linea alba with an abnormal increase in the distance between the recti without a concomitant fascial defect.

Cyclin Dependent Kinase 9 (CDK9), which controls transcriptional elongation, is a promising pharmacological target for a variety of cancerous cells, specifically those characterized by transcriptional dysregulation. CDK9 promotes the pause or release of RNA polymerase II, a rate-limiting stage in normal transcriptional regulation that is often disturbed in cancers. New indications suggest that selective CDK9 antagonism may be beneficial in the treatment of some cancers.

X chromosome activity is a defining attribute of naive pluripotency, with naive pluripotency being a rare context in which both X chromosomes of females are active. RNA-fluorescence in situ hybridization (RNA-FISH) is a powerful tool to determine the transcriptional status of specific genes with allelic and single-cell resolution and has been widely used in the context of X chromosome inactivation, the process ensuring dosage compensation for X-linked genes between sexes in mammals. RNA-FISH using genomic or intronic probes allows the detection of newly synthesized transcripts at the site of transcription.
