Article Synopsis
  • Wild pomegranate is a medicinal plant with significant health benefits, but its genome has not been fully understood until this study, which provides the first comprehensive genomic assembly.
  • The researchers assembled a genome of 279.0 Mb, predicting 49,178 genes with key functions related to metabolism and stress responses, and identified transcription factors and transposable elements.
  • The study also included a comparative analysis of the wild pomegranate genome against cultivated varieties and other plant species, helping to uncover evolutionary relationships and gene functions, especially in terpenoid biosynthesis.

Gut dysbiosis and liver cirrhosis are two corelated complications that highly disturbs the metabolism of a normal human body. Liver cirrhosis is scarring of the hepatic tissue and gut dysbiosis is the imbalance in the microbiome of the gut. Gut dysbiosis in cirrhosis occurs due to increased permeability of the intestinal membrane which might induce immune responses and damage the normal functioning of the body.

Background And Objectives: Cadherin13 () is an uncommon cadherin family member, lacking a transmembrane domain, and attaches via a glycosylphosphatidylinositol anchor to the peripheral surface of the cell membrane. plays an important role in the development and maintenance of axonal growth cones, synapse morphogenesis, and the embryonic neural tube. Cadherin superfamily genes have been associated with many neuropsychiatric diseases.

Current study is the first report of the combined application of chemical (deep eutectic solvent), physical (microwave irradiation) and biological (laccase) pretreatment strategies for enhancing the enzymatic digestibility of rice straw biomass. Pretreated rice straw biomass was saccharified by cellulase/xylanase from Aspergillus japonicus DSB2 to get a sugar yield of 252.36 mg/g biomass.

Background: Neurogenic locus notch homolog 4 () regulates signaling pathways associated with neuronal maturation, a process involved in the development and patterning of the central nervous system. The gene has also been identified as a possible susceptibility gene for schizophrenia (SCZ).

Aim: The study aimed to determine the association of polymorphisms with the risk of SCZ in the North Indian population of the Jammu region.

Julian Go's 'Thinking Against Empire' identifies the corpus of 'anticolonial thought' as being instructive for a wider rethinking of how sociology might rally its key conceptualisations of social relations. He insightfully identifies the marginalisation of such thinking from Sociology as an institutionalised discipline. In our response we take up some of the warnings Go provides in the closing sections of his essay-which concern the expanse of intellectual engagement being currently bracketed under or connected to the 'anti-colonial', not least vis-à-vis the 'decolonising/decolonial' turn-to further unpack how the 'anti-colonial' might be adapted for thinking through contemporary socio-political dynamics.

, known for its pharmacological properties, produces a plethora of structurally stable peptides called cyclotides. Cyclotides are macrocyclic peptides with a unique topology containing a cyclic cystine knot motif. The objective of the present study was to identify the precursor sequences and respective cyclotide domains from the petiole tissue of .

This work aimed to study the hydrolysis of ionic liquid (IL) pretreated sugarcane tops (SCT) biomass with in-house developed IL-stable enzyme preparation, from a fungal isolate Aspergillus flavus PN3. Maximum reducing sugar yield (181.18 mg/g biomass) was obtained from tris (2-hydroxyethyl) methylammonium-methylsulfate ([TMA]MeSO) pretreated biomass.

Unlabelled: Cyclotides are true gene products characterized by the presence of six conserved cysteine residues and knotted arrangement of three disulfide bonds. These macrocyclic peptides show exceptional resistance to thermal, chemical and enzymatic degradation which is defined due to their three-dimensional folding. The current study describes an efficient strategy involving reduction, enzymatic digestion and mass spectroscopy sequencing for the identification of the precursor sequences and the cyclotide domains present in the leaf tissue of .

The diversity on fruit colouration in plants directly depends on the flavonoids that explain the development of different pigmentation patterns. Anthocyanins are the major class of flavonoid pigments that are synthesized through flavonoid biosynthetic pathway. In the present study, two genes: UFGT gene and R2R3-MYB gene, involved in anthocyanin biosynthesis were analysed in four tissues of wild pomegranate.

Context: Pancreatic fistulae are uncommon and usually follow acute or chronic pancreatitis. While most of these are treated conservatively, some require surgery. Recently endoscopic therapy has emerged as an effective alternative treatment modality.

Cationic amino acid transporters (mCAT1 and mCAT2B) regulate the arginine availability in macrophages. How in the infected cell a pathogen can alter the arginine metabolism of the host remains to be understood. We reveal here a novel mechanism by which Salmonella exploit mCAT1 and mCAT2B to acquire host arginine towards its own intracellular growth within antigen presenting cells.

Background: Acute abdominal pain is commonly encountered in the emergency department (ED), but a diagnosis of gall bladder perforation (GBP) is rarely considered in the absence of predisposing factors.

Objectives: This article will highlight the risk factors, diagnosis, and management of GBP, a rare but potentially life-threatening biliary pathology.

Case Report: A 73-year-old diabetic man presented to the ED with a 12-h history of severe upper abdominal pain.

Mycobacterium tuberculosis utilizes unique strategies to survive amid the hostile environment of infected host cells. Infection-specific expression of a unique mycobacterial cell surface antigen that could modulate key signaling cascades can act as a key survival strategy in curtailing host effector responses like oxidative stress. We demonstrate here that hypothetical PE_PGRS11 ORF encodes a functional phosphoglycerate mutase.

Pathogenic mycobacteria have evolved unique strategies to survive within the hostile environment of macrophages. Modulation of key signaling cascades by NO, generated by the host during infection, assumes critical importance in overall cell-fate decisions. We show that NO is a critical factor in Mycobacterium bovis bacillus Calmette-Guérin-mediated Notch1 activation, as the generation of activated Notch1 or expression of Notch1 target genes matrix metalloproteinase-9 (MMP-9) or Hes1 was abrogated in macrophages derived from inducible NO synthase (iNOS) knockout (iNOS(-/-)), but not from wild-type, mice.

Initiation of proinflammatory host immunity in response to infection represents as a key event in effective control and containment of the pathogen at the site of infection as well as in elicitation of robust immune memory responses. In the current investigation, we demonstrate that an integral cell wall antigen of the mycobacterial envelope, Phosphatidyl-myo-inositol dimannosides (PIM2) triggers Suppressor of cytokine signaling (SOCS) 3 expression in macrophages in a Toll-like receptor 2 (TLR2)-MyD88 dependent manner. Data derived from signaling perturbations suggest the involvement of phosphoinositide-3 kinase (PI3K) and protein kinase C (PKC) signaling pathways during PIM2 induced SOCS3 expression.

Activation of inflammatory immune responses during granuloma formation by the host upon infection of mycobacteria is one of the crucial steps that is often associated with tissue remodeling and breakdown of the extracellular matrix. In these complex processes, cyclooxygenase-2 (COX-2) plays a major role in chronic inflammation and matrix metalloproteinase-9 (MMP-9) significantly in tissue remodeling. In this study, we investigated the molecular mechanisms underlying Phosphatidyl-myo-inositol dimannosides (PIM2), an integral component of the mycobacterial envelope, triggered COX-2 and MMP-9 expression in macrophages.

Purpose Of Review: There is controversy about the best approach to screening and management for gestational diabetes. In the recent Confidential Enquiry in Maternal and Child Health (CEMACH) the outcome of women with diabetes compared with women without diabetes. The results were exceptionally poor, suggesting the need for a new management approach.
