Antifertility activity of Oroxylum indicum (L.) Kurz:In vitro and in vivo study on human sperm and male wistar rats
Oroxylum indicum (L.) Kurz, commonly called as Broken bones tree or Indian trumpet flower, belonging to Fam. Bignoniaceae, is traditionally used as a contraceptive by ethnic people of Tripura, North-East India. Here, we investigated the scientific basis for use of O. indicum as male antifertility agent by folklore healers. In vitro spermicidal activity of aqueous (AEOI) and methanolic (MEOI) extracts of O. indicum stem bark were studied on human sperm. The in vivo activity was experimented on male albino rats. The treated animals were allowed to mate and the pups delivered by female rat partners were counted. Phytochemical estimation of test samples was done using HPLC. The AEOI and MEOI treatments significantly decreased human sperm motility and viability. Test extracts have increased the hypo-osmotic swelling of sperm. Both the extracts were significantly declined the weight of reproductive organ. The MEOI treated rats have shown significant decrease in sperm motility and sperm counts. AEOI and MEOI treatment significantly reduced level of testosterone, but sharply raised dihydrotestosterone and prostaglandin in rats. Results testified the traditional claim for use of O. indicum as a male contraceptive agent, where MEOI have shown reversible action on male reproductive system leading to contraception without harming the libido
CLINICAL MANAGEMENT OF LOCALIZED BCG ADVERSE EVENTS IN CHILDREN
SUMMARY BCG adverse events (BCG-AE) are rare conditions with no well-established treatment. This study aims to describe clinical characteristics and outcome of localized BCG-AE. Children with BCG-AEs who were treated at the Reference Center for Special Immunobiologicals of the Federal University of São Paulo from 2009 to 2011 were included. Patients were followed monthly until 3 months after healing. One hundred and twenty-seven patients with localized BCG-AE were followed: 67 (52.7%) had suppurative lymphadenitis; 30 (23.6%) injection-site abscess; five (3.9%) had enlarged lymph node > 3 cm; four (3.1%) had ulcer > 1 cm; and one (0.8%) had a local bacterial infection. Five patients (3.9%) had more than one BCG-AE simultaneously. Fifteen patients (11.8%) had atypical manifestations: seven wart-like lesions; five BCG reactivations; two other dermatologic lesions and one with vasomotor phenomenon. Isoniazid was used in 96 patients with typical BCG-AE (85.7%) until lesion resolution which took place 3.1 months later (in median); the healing rate was 90.6%. Patients with atypical manifestations had an individual approach. Regarding the outcome, 105/112 patients with typical AE and 13/15 patients with atypical AE had resolution of BCG-AE. Localized BCG-AE caused by BCG Moreau RJ had positive outcome when treated with a short course of isoniazid. Atypical BCG-AE are not infrequent

624-628Rasausadhies or
organo-metallic formulations have
been use in the treatment of Diabetes mellitus with its excellence for
centuries but their scientific evaluation has not thoroughly constituted with
modern tools. Rasausadhies are popularly use since the period of great alchemist
Nagarjuna, i.e. 8th century AD. In fact, it is explored that strategies and
treatment modalities to control diabetes exists in Rasashastra, a discipline of Ayurveda. In this time, invention of
special processing techniques as sodhan (purification
and detoxification), marana (incineration), etc. have been established which are
being use to convert the minerals and metals into easily consumable form and
immediate showing the desirable effect. Madhumeha
(Diabetes mellitus) is a multi-factorial disease resulting from a gene
environment interaction. Projection of disease prevalence and incidence rate in
worldwide by World Health Organization indicating the danger and graveness of
this disease. In the present study, the initiation have been taken to collect
and compiled all the related information about Madhumeha with current evidence regarding Rasausadhies used therapeutically that may facilitate further

Static Permittivity and Electro-Optical Properties of Bi-Component Orthoconic Antiferroelectric Liquid Crystalline Mixtures Targeted for Polymer Stabilized Sensing Systems
The behavior of two newly formulated bi-component orthoconic antiferroelectric liquid crystalline (OAFLC) systems, i.e., the Compound A + Compound B mixture system and Compound C + Compound B mixture system has been discussed in light of temperature and concentration dependencies of helical pitch length, spontaneous polarization, relaxation time, bulk viscosity, and the anchoring energy strength coefficient, together with static dielectric permittivity (ε) and dielectric anisotropy. Compound A + Compound B mixtures possess spontaneous polarization between 190–340 nC.cm−2 and fast relaxation times between 190–320 µs in the smectic antiferroelectric SmCA* phase at room temperature. Compound C + Compound B mixtures also have a spontaneous polarization in the range of 190–280 nC.cm−2 and relaxation times in the range of 190–230 µs at room temperature. Most of the mixtures have a helical pitch below one micrometer in the SmCA* phase. These advanced mixtures show a broad temperature range of the antiferroelectric SmCA* phase, fast switching of molecules under an applied electric field, negative dielectric anisotropy and a short helical pitch, confirming the advantage of designing new polymer-stabilized OAFLC that is targeted for novel application in sensing devices, utilizing the fast responsive electro-optical modulation elements
Ferroelectric and antiferroelectric chiral multilactate liquid crystalline materials with negative dielectric anisotropy
In this work, the mesomorphic, electro-optic and dielectric properties have been discussed in the light of molecular structure-property correlations of two chiral multilactate liquid crystalline materials possessing the orthogonal paraelectric Smectic A* phase, tilted ferroelectric Smectic C* phase and the tilted antiferroelectric Smectic CA* phase, over a substantially broad temperature range. Interestingly, a reasonably rare re-entrant Smectic C* phase (SmCre*) has also been identified in one of the investigated materials. These materials differ in their linkage groups (keto or ether) and an additional chiral unit in the terminal chain. The phase transition temperatures and transition enthalpies were determined from Polarizing Optical Microscopy and Differential Scanning Calorimetry (DSC) measurements. The compounds exhibit negative dielectric anisotropy (Δε) throughout the mesomorphic range (maximum −18 and −4 in SmA* for both the compounds) and moderately high values of spontaneous polarization (∼153 nC/cm2 in SmCre* phase). The temperature dependence of the response time (τ), bulk viscosity (η) and the activation energies (Ea) throughout the mesomorphic phase have been determined from the spontaneous polarization measurements. To emphasize the structure-property correlations in more detail, dielectric spectroscopy measurement has also been performed to measure the dielectric strength, dielectric loss, frequency dependent permittivities, relaxation time and relaxation frequencies. The clear evidence of the relatively rare SmCre* phase has also been confirmed from the temperature and frequency dependence of the dielectric permittivity. These results shed important light on the emergence of these materials as a smart alternative for their application in multicomponent mixtures targeted for advanced electro-optic and photonic devices

Curcumin ameliorates the targeted delivery of methotrexate intercalated montmorillonite clay to cancer cells
Montmorillonite Clay (MMT) is aimed to develop as an orally administrable drug delivery vehicle with enhanced efficacy. Aiming to enhance the therapeutic index of methotrexate, curcumin is concomitantly used with methotrexate in the present study. Being folate antagonist in nature, methotrexate is internalized into cells by folate receptor (FR); which is over-expressed in certain human cancer cells such as cervical carcinoma cells (HeLa). Firstly, montmorillonite Clay (MMT) is organically modified (OMMT) with cetyl trimethyl ammonium bromide (CTAB) and used to intercalate curcumin and methotrexate separately, designated as OMMT-Cur and OMMT-MTX, respectively. XRD pattern demonstrated successful intercalation of therapeutics and an increase in clay interlayer distance facilitated by CTAB. The dissolution kinetics of methotrexate follows Higuchi model for both Simulated Gastric Fluid (SGF) and Simulated Intestinal Fluid (SIF), while the release kinetics for curcumin fitted into Higuchi model for SGF and Hixson-Crowell model for SIF, respectively. OMMT-MTX are able to discriminate FR-positive HeLa cells from FR-negative breast cancer cells (MCF7); irrespective of alike cellular phenotypes. Further, the pre-treatment of HeLa cells with curcumin improves its sensitivity towards metho- trexate causing a greater killing of the Hela cells. Together, the results propose the concomitant use of curcumin and methotrexate for successfully targeting highly invasive FR-positive carcinomas by means of folate receptor using MMTs.This work was supported by European Union (Horizon 2020) funded project FoReCaST(Grant Agreement Number 668983)(BK).info:eu-repo/semantics/publishedVersio
