Antidiabetic Effects of Momordica Charantia (Karela) in Male Long Evans Rat
The hypoglycemic effect of Momordica charantia (Karela) has been reported from many laboratories. To our knowledge, the underlying biochemical mechanism of action of this important clinical effect has not been reported. During the course of investigation of this aspect of the herbal fruit, it was reported from our laboratory that ethanolic extract of Momordica charantia suppressed gluconeogenesis in normal and streptozotocin (STZ) induced diabetic rats by depressing the hepatic gluconeogenic enzymes fructose-1,6-bisphosphatase and glucose-6-phosphatase. The herbal extract had also enhanced the activity of glucose-6-phosphate dehydrogenase, the rate-limiting enzyme of hexose monophosphate shunt (a pathway for the oxidation of glucose)
INNOVATIVE HUMAN RESOURCE MANAGEMENT AND MARKETING POLICIES FOR EXPANDING HEALTHCARE REACH IN RURAL AREAS
Access to quality healthcare in rural areas remains a significant global challenge, requiring innovative approaches in both human resource management (HRM) and marketing strategies. This paper explores how innovative HRM practices, such as telemedicine workforce training, decentralized healthcare staffing, and performance-based incentives, can enhance healthcare delivery in underserved regions. Additionally, marketing policies, including community-based engagement, digital outreach, and social entrepreneurship models, are examined to increase healthcare awareness and utilization. By integrating strategic HRM and targeted marketing efforts, healthcare organizations can bridge the rural-urban healthcare divide, improve patient outcomes, and ensure long-term sustainability
Therapeutic and immunomodulatory activities of short-course treatment of murine visceral leishmaniasis with KALSOME™10, a new liposomal amphotericin B
Visceral leishmaniasis (VL), a potentially fatal disease, is most prevalent in the Indian subcontinent,
East Africa and South America. Since the conventional antileishmanial drugs have many limitations we evaluated a
new ergosterol rich liposomal amphotericin B formulation, KALSOME™10 for its leishmanicidal efficacy, tolerability
and immunomodulatory activity. Normal healthy mice were treated with 3.5 mg/kg single and 7.5 mg/kg single and double doses ofKALSOME™10. Liver and kidney function tests were performed fourteen days after treatment. Next, normal mice were infected with Leishmania donovani amastigotes. Two months post infection they were treated with the above
mentioned doses of KALSOME™10 and sacrificed one month after treatment for estimation of parasite burden in
the liver and spleen by Limiting Dilution Assay. Leishmanial antigen stimulated splenocyte culture supernatants were collected for cytokine detection through ELISA. Flow cytometric studies were performed on normal animals treated with KALSOME™10, Amphotericin B (AmB) and AmBiosome to compare their immunomodulatory activities.
The drug was found to induce no hepato- or nephrotoxicities at the studied doses. Moreover, at all doses,
it led to significant reduction in parasite burden in two month infected BALB/c mice, with 7.5 mg/kg double dose
resulting in almost complete clearance of parasites from both liver and spleen. Interestingly, the drug at 7.5 mg/kg
double dose could almost completely inhibit the secretion of disease promoting cytokines, IL-10 and TGFβ, and
significantly elevate the levels of IFNγ and IL-12, cytokines required for control of the disease. Mice treated with KALSOME™10 showed elevated levels of IFNγ and suppressed IL-10 secretion from both CD4+ and CD8+ subsets
of T cells, as well as from culture supernatants of splenocytes, compared to that of normal, AmB and AmBisome
treated animal Treatment of infected mice with 7.5 mg/kg double dose of KALSOME™10 was safe and effective in
clearing the parasites from the sites of infection. The drug maintains the inherent immunomodulatory activities of
AmB by effectively suppressing disease promoting cytokines IL-10 and TGFβ, thereby boosting IL-12 and IFNγ levels.
This emphasizes KALSOME™10 as a promising drug alternative for lifelong protection from VL
Tunable magnetic domains in ferrimagnetic MnSbTe
Highly tunable properties make Mn(Bi,Sb)Te a rich playground for
exploring the interplay between band topology and magnetism: On one end,
MnBiTe is an antiferromagnetic topological insulator, while the
magnetic structure of MnSbTe (MST) can be tuned between
antiferromagnetic and ferrimagnetic. Motivated to control electronic properties
through real-space magnetic textures, we use magnetic force microscopy (MFM) to
image the domains of ferrimagnetic MST. We find that magnetic field tunes
between stripe and bubble domain morphologies, raising the possibility of
topological spin textures. Moreover, we combine in situ transport with domain
manipulation and imaging to both write MST device properties and directly
measure the scaling of the Hall response with domain area. This work
demonstrates measurement of the local anomalous Hall response using MFM, and
opens the door to reconfigurable domain-based devices in the M(B,S)T family
Numerical Model for Hydraulic Performance of Under-drained Perforated Pipe Surrounded by Loose Aggregate
Urbanization significantly alters the hydrological cycle, leading to reduced infiltration, increased flooding, and reduced water quality. Proper management of storm-water runoff is necessary to mitigate these undesired impacts. The use of Best Management Practices (BMP) and Low Impact Development (LID) is becoming more common day by day for this purpose and perforated pipes are one of the main components of these LIDs and BMPs. This poster presents results from a CFD model that combines both porous media flow and pipe flow. The model was developed in ANSYS FLUENT to examine the hydraulic behavior (stage-discharge relationship) of a porous pipe shrouded in loose aggregate for use as an underdrain in storm water management. The model was validated against the experimental data of Murphy et al. (2014) and was then used to undertake a detailed parametric study of porous pipe underdrain performance

Controlling calibration errors in gravitational-wave detectors by precise location of calibration forces
We present results of finite element analysis simulations which could lead to more accurate calibration of interferometric gravitational wave detectors. Calibration and actuation forces applied to the interferometer test masses cause elastic deformation, inducing errors in the calibration. These errors increase with actuation frequency, and can be greater than 50% at frequencies above a few kilohertz. We show that they can be reduced significantly by optimizing the position at which the forces are applied. The Advanced LIGO [1] photon calibrators use a two-beam configuration to reduce the impact of local deformations of the test mass surface. The position of the beams over the test mass can be chosen such both the local and the bulk induced elastic deformation are minimized. Our finite element modeling indicates that with two beams positioned within ±1 mm of their optimal locations, calibration errors due to test mass elastic deformation can be kept below 1% for frequencies up to 3.5 kHz. We thus show that precise control of the location of calibration forces could considerably improve calibration accuracy, especially at high frequencies
Formulate and evaluate once daily sustained release tablet of highly soluble drug of metformin HCL
The aim of the present study was to design an oral sustained release matrix tablet of highly water soluble biguanide anti diabetic drug. The matrix tablets are prepared by melt granulation method using HPMC K 200M as hydrophilic drug release retarding polymer, and stearic acid as melt able binder as well as hydrophobic carrier. The drug and excipients compatibility was studied by FT – IR. The formulated matrix tablets were characterized for physical parameters and in vitro dissolution profile. FT – IR spectra revealed the absence of drug excipients interaction. The physical parameters of the tablets were found within the limits. The drug release kinetics demonstrated that by increasing the concentration of hydrophilic polymer and hydrophobic carrier the drug release rate was retarded proportionally. Kinetic modelling of in vitro release profile revealing that the drug release from the matrix tablets following first order kinetics, and the drug release mechanism of optimized (F7) formula following non fickian transport mechanism. Accelerated stability studies were performed according to ICH guide lines. Temperature 40±20 c and relative humidity 75±5% RH to study physical and chemical changes of formulation. No physical or chemical changes were observed after t accelerated stability studies
Hydrogen induces chiral conduction channels in the topological magnet
Chirality, a characteristic handedness that distinguishes 'left' from
'right', cuts widely across all of nature, from the structure of DNA to
opposite chirality of particles and antiparticles. In condensed matter
chiral fermions have been identified in Weyl semimetals through their
unconventional electrodynamics arising from 'axial' charge imbalance between
chiral Weyl nodes of topologically nontrivial electronic bands. Up to now it
has been challenging or impossible to create transport channels of Weyl
fermions in a single material that could be easily configured for advancing
chiral logic or spintronics. Here we generate chirality-directed
conduction channels in inversion-symmetric Weyl ferromagnet (FM) ,
emergent from a deep connection between chirality in reciprocal and real space.
We alter the bandstructure on-demand with an intake and a subsequent release of
ionic hydrogen () a process we show to induce the tilt and rotation of
Weyl bands. The transformed Weyl FM states feature a doubled Curie temperature
and an enhanced angular transport chirality synchronous with a rare
field-antisymmetric longitudinal resistance a low-field tunable 'chiral
switch' that roots in the interplay of Berry curvature, chiral anomaly
and hydrogen-engendered mutation of Weyl nodes
