Human leucocyte antigen (HLA) represents one of the most highly polymorphic systems which plays a central role in immune response. Genetic polymorphism HLA influenza A(H1N1)pdm09 infected population may be an important factor disease progression and severity that needs further probing. In this study, total 110 Influenza like illness patients were recruited from Assam, Northeast India, 35 cases by viruses controls typed for HLA-A, B DRB1 locus PCR-SSP method. A seven alleles 16 HLA-B, 11...
Abstract Mitochondrial dysfunction due to oxidative damage is the key feature of several diseases. We have earlier reported mitochondrial resulting from generation stress as a major pathophysiological effect isoproterenol (ISO)‐induced myocardial ischemia in rats. That melatonin an antioxidant that ameliorates experimental animals well humans established. previously demonstrated provides cardioprotection against ISO ‐induced injury result its properties. The mechanism cardiac and protection...
Piperine, the main alkaloid of black pepper, Piper nigrum Linn., is an important Indian spice used in traditional food and medicine India. In present study, we investigated antioxidant activities piperine against copper-ascorbate induced toxic injury to mitochondria obtained from a goat heart, vitro. Incubation isolated cardiac with resulted elevated levels lipid peroxidation protein carbonylation mitochondrial membrane, reduced level GSH altered status enzymes as well decreased pyruvate...
Purpose The present study explored the molecular characterization of human Adenovirus (HAdV) and its strains among hospitalized SARI cases in pediatric unit a tertiary care hospital North-East India. Methods Nasal throat swabs were collected from 70 patients Pediatric Unit, NE India April 2023-October 2023. samples screened for presence HAdV using an adenovirus-specific Real-Time PCR Kit. For characterization, Next Generation Sequencing (NGS) was performed by targeting hexon gene followed...
Background: Hypertension is the most frequently encountered medical disorder in obstetrics practice & remain a major cause of maternal, fetal neonatal morbidity mortality. The present study was undertaken to compare time taken reach therapeutic goal blood pressure after using intravenous labetalol oral nifedipine severe pregnancy induced hypertension. Methods: Randomly allocated patients received 20 mg initially, followed by escalating doses 40, 80, 80 placebo tablet every minutes or...
Spin-crossover materials exhibit thermal conversion of their electronic state from low to high spin, involving both intra- and inter-molecular structural reorganisations, eventually accompanied by symmetry breaking, within the crystal.
Background: Foods not commonly consumed in the European Union must be proven safe before being brought to market, including an assessment of allergenicity. We present a three‐stepwise strategy for allergenicity natural novel foods using three vegetables, namely, water spinach, hyacinth bean, Ethiopian eggplant. Methods: First, vegetable extracts were analyzed presence pan‐allergens [Bet v 1 homologous proteins, profilins, nonspecific lipid transfer proteins (LTP)] by immunoblot analysis with...
Background. Epidemiological studies consistently demonstrate synergy between herpes simplex virus type 2 (HSV-2) and human immunodeficiency 1 (HIV-1). Higher HIV-1 loads are observed in coinfected individuals, conversely, is associated with more-severe herpetic disease. A small animal model of coinfection would facilitate identification the biological mechanisms underlying this provide opportunity to evaluate interventions. Methods. Mice transgenic for provirus cyclin T1 under control a CD4...
The thermal spin transition and the photo-induced high-spin → low-spin relaxation of prototypical [Fe(ptz)6](BF4)2 spin-crossover compound (ptz = 1-propyltetrazole) diluted in isostructural ruthenium host lattice [Ru(ptz)6](BF4)2, which stabilizes Fe(II) state, have been investigated. We demonstrate presence a crystallographic phase around 145 K (i.e. from high-temperature ordered to low-temperature disordered phase) upon slow cooling room temperature. This is decoupled transition. A...

Influenza A(H1N1)pdm09 virus, since its identification in April 2009, has continued to cause significant outbreaks of respiratory tract infections including pandemics humans. In the course evolution, virus acquired many mutations with an ability increased disease severity. A regular molecular surveillance is essential mark evolutionary changes that may a shift viral behavior.Samples Throat/Nasal swabs were collected from total 3715 influenza-like illness cases and screened by Real-time...
Structural studies involving single-crystal and powder X-ray diffraction analysis have been performed on dehydrated coordination networks of the [NixCo1-x(bpy)3][LiCr(ox)3] series, 0 ≤ x 1, (bpy = 2,2'-bipyridine). The high-symmetry cubic 3D structure these materials is formed by oxalate anions bridging alternating Cr3+ Li+ ions into an anionic framework, which contains large cavities that incorporate [NixCo1-x(bpy)3]2+ cations. Irrespective Co/Ni ratio, all mixed samples are phase-pure...
Introduction: Vitamin B12 (vit B12) deficiency is a preventable disorder and has dire consequences on the neurological development of infant. The only source vit for exclusively breastfed newborns their mother’s milk. So, determining status maternal levels during early lactation vital. In India, very few studies have documented among lactating mothers, especially eastern region remains unexplored. Aim: To estimate prevalence healthy mothers attending postpartum clinic at six weeks Tertiary...
The magnetic transition in spin-crossover (SCO) materials with temperature is a dynamic and reversible process, which the metal ions change from low spin (LS) state to high (HS) state. This work reports extraordinary dielectric transitions at 342 382 K reflected capacitance fabricated Fe-based SCO material. These are predominantly instigated its nanomaterial phase thin film-based devices. However, similar devices bulk material did not show any significant changes. associated occur without...
Newly synthesized Co(II)-Cltpy-based spin-crossover molecular materials involving ClO4-, BF4-, PF6-, and CF3SO3- are systematically investigated by emphasizing the structure-property interplay. The multi-facet character of ligand, 4′-Chloro-2,2′:6′,2′′-terpyridine (Cltpy) makes the...
Introduction: The pathogenicity of influenza virus infection is modulated by the cytokine expressions in patients. present study was aimed to measure some important pro- and anti-inflammatory cytokines influenza-infected population Assam, Northeast India. Materials Methods: Influenza viruses consisting subtypes A(H1N1)pdm09, H3N2 influenza-B were detected patients with symptoms influenza-like-illness Real-time reverse transcriptase polymerase chain reaction (RT-PCR) method.

Background: For patients with food allergy there has been no alternative treatment to allergen avoidance. In a study supported by the European union, new approach aimed reduce allergenicity of foods animal origin achieve better tolerance. Patients and methods: prevalence was assessed telephone interviews more than 40000 persons in 10 countries. By thermal enzymatic allergens hen's egg, cow's milk, beef poultry reduced. proven those were recruited allergologically. In-vitro cellular test...
