HIV/AIDS patients have suppressed immune system, making them vulnerable to many opportunistic infections including tuberculosis (TB). The patients who are co-infected with TB undergo combined regimens with anti-retroviral drugs such as zidovudine (AZT) and anti-tubercular drug such as isoniazid (INH) for therapy leading to hepatotoxicty. Silibinin (SBN), extracted from Silybum marianum commonly called as "Milk thistle" is used against several drugs-induced hepatotoxicity. The present study evaluates the ameliorative effect of SBN against AZT alone, INH alone, and INH + AZT-induced toxic insults to liver of rats...

Sweet syndrome is a prototypical neutrophilic dermatosis, a class of inflammatory diseases marked by elevated levels of tumor necrosis factor (TNF)-α and IL-17A, pathologic neutrophil recruitment, and microvascular remodeling. Histologic analyses of four matrix proteins-collagen I and IV, laminin, and fibronectin-in the skin biopsies of patients with Sweet syndrome reveal that the basement membrane of dermal postcapillary venules undergoes changes in structure and composition. Increased neutrophil recruitment in vivo was associated with increases in collagen IV, decreases in laminin, and varied changes in fibronectin...

Recent years have seen an increase in the use of nebulizers for delivering maintenance therapy in obstructive airway diseases (OADs) such as asthma and chronic obstructive pulmonary disease (COPD). The probable factors associated with this increase at home are: convenience of drug delivery, technological advances making the nebulizer equipment more efficient and portable, increase in the prevalence of OADs and the ageing population which may impact the optimal use of handheld inhalers such as pressurized metered dose inhalers (pMDIs) and dry powder inhalers (DPIs)...

Central skull base osteomyelitis is a rare, but potentially life-threatening disease entity often lacking otologic symptoms or external auditory canal pathology. We present a case of a man in his 70s who had developed cranial nerve deficits with radiographic evidence that was consistent with a tumor due to this uncommon entity. The radiologic findings and our experience are discussed to increase awareness in the otolaryngology community.

This paper reports results of (23)Na and (29)Si solid-state NMR investigations carried out on sodium strontium silicate ion conductor, Sr0.55Na0.45SiO2.775 and presents the first experimental evidence to show that different synthesis conditions induce multiple devitrified phases. Along with 1-dimensional NMR, (23)Na MQMAS spectra have been used to identify the phases corresponding to polymorphs of Na2Si2O5, in addition to the crystalline SrSiO3 and the glass/amorphous Na2Si2O5 phases. The surprising observation of about an order of magnitude higher ionic conductivity achieved in devitrified samples is attributed to the growth of the crystalline δ-Na2Si2O5 phase within the amorphous Na2Si2O5 phase domains, identified using NMR...

Naturally occurring and synthetic carbohydrate amphiphiles have emerged as a promising class of antimicrobial and antiadhesive agents that act through a number of dynamic and often poorly understood mechanisms. In this paper, we provide the first report on the application of azobenzene trans-cis photoisomerization for effecting spatial and temporal control over bacterial growth and biofilm formation using carbohydrate-based surfactants. Photocontrollable surface tension studies and small angle neutron scattering (SANS) revealed the diverse geometries and dimensions of self-assemblies (micelles) made possible through variation of the head group and UV-visible light irradiation...

The scrotal wall may be involved in a variety of pathologic processes. Such lesions may rise primarily from the layers of the scrotum or may be due to a process arising from scrotal content. Imaging is not needed in most cases, but it may be useful for making such differentiations and for evaluation of possible involvement of the testes and epididymides in cases of primary wall abnormalities. This pictorial essay will show the imaging findings observed in a variety of pathologic conditions affecting the scrotal wall, both common and unusual ones, with an emphasis on clinically relevant findings and features that lead to a specific diagnosis...

We report a nanosensor that uses cell lysates to rapidly profile the tumorigenicity of cancer cells. This sensing platform uses host-guest interactions between cucurbit[7]uril and the cationic headgroup of a gold nanoparticle to non-covalently modify the binding of three fluorescent proteins of a multi-channel sensor in situ. This approach doubles the number of output channels to six, providing single-well identification of cell lysates with 100% accuracy. Significantly, this classification could be extended beyond the training set, determining the invasiveness of novel cell lines...

Few-layer black phosphorous (BP) has emerged as a promising candidate for next-generation nanophotonic and nanoelectronic devices. However, rapid ambient degradation of mechanically exfoliated BP poses challenges in its practical deployment in scalable devices. To date, the strategies employed to protect BP have relied upon preventing its exposure to atmospheric conditions. Here, an approach that allows this sensitive material to remain stable without requiring its isolation from the ambient environment is reported...
