Hydrogen sulfide (H2 S) together with polysulfides (H2 Sn , n > 2) are signalling molecules like NO with various physiological roles including regulation of neuronal transmission, vascular tone, inflammation and oxygen sensing. H2 S and H2 Sn diffuse to the target proteins for S-sulfurating their cysteine residues that induces the conformational changes to alter the activity. On the other hand, 3-mercaptopyruvate sulfurtransferase transfers sulfur from a substrate 3-mercaptopyruvate to the cysteine residues of acceptor proteins. A similar mechanism has also been identified in S-nitrosylation. S-sulfuration and S-nitrosylation by enzymes proceed only inside the cell, while reactions induced by H2 S, H2 Sn and NO even extend to the surrounding cells. Disturbance of signalling by these molecules as well as S-sulfuration and S-nitrosylation causes many nervous system diseases. This review focuses on the signalling by H2 S and H2 Sn with S-sulfuration comparing to that of NO with S-nitrosylation and discusses on their roles in physiology and pathophysiology.A key recommendation of the National AIDS Control Programme-IV of India was to develop new strategies for geo-prioritization of the human immunodeficiency virus (HIV) epidemic. We conducted this study to categorize the districts in Maharashtra (India) based on a multidimensional framework for geo-prioritization of services. Programmatic data on trends of HIV prevalence, coverage of marginalized populations and vulnerability factors were included. A composite indicator based on these was developed, and the cumulative score was calculated for each district. HIV prevalence among general population has declined steadily from 0.60% in 2007 to 0.33% in 2017. The programme coverage was stable but inadequate for men who have sex with men (MSM). The coverage for female sex workers (FSWs) was inadequate and reduced over time. Nine districts were categorized as high priority, 13 as moderate priority and 11 were classified as low-priority districts based on burden and vulnerability for HIV. The high-priority districts were Pune, Solapur and Yavatmal for FSW interventions and Pune, Thane and Latur for MSM interventions. This multidimensional indicator is based on existing programmatic data, dynamic and can be made state-specific. It is useful to categorize and prioritize districts for allocation of resources and geo-prioritization of services in resource limited settings.Organic compounds with electronic properties, such as a small band gap, are useful in areas ranging from organic field effect transistors to solar cells. Such organic compounds can possess conjugation and/or aromatic systems, with one example being tetraphenylcyclopentadienone and its derivatives. A trio of dramatically coloured tetraphenylcyclopentadienone derivatives with varied substituents on the aromatic rings in the 3- and 4-positions were prepared. Their identities were confirmed using the usual methods, for example 1 H nuclear magnetic resonance (NMR) spectroscopy, and their purity quantified using elemental analysis. The X-ray crystal structure of compound 2 was determined. Its notable structural features involved the cyclopentadienone core with its distinct C-C and C=C bond lengths and its overall nonplanarity, both of which served to mitigate its antiaromatic nature. Chloroform solutions of compounds 2-4 exhibited absorption spectra with three absorption bands at approximately 250, 350, and 500 nm that were assigned to (π)→(π*) transitions. Computational chemistry methods assisted in assigning the observed transitions to a specific molecular orbital combination in the structures of 2-4. Emission in the red end of the visible spectrum (550-625 nm) was observed from chloroform solutions of all three of the prepared compounds.Aluminium salts have been used in vaccines for decades. However, the mechanisms underlying their adjuvant effect are still unclear. Neutrophils, the first immune cells at the injection site, can release cellular DNA together with granular material, so-called neutrophil extracellular traps (NETs). In mice, NETs apparently play a role in aluminium hydroxide (alum)-adjuvant immune response to vaccines. Although no experimental data exist, this effect is assumed to be operative also in humans. As a first step to verify this knowledge in humans, we demonstrate that the injection of alum particles into human skin biopsies ex vivo leads to similar tissue infiltration of neutrophils and NET-formation. Moreover, we characterized the mechanism leading to alum-induced NET-release in human neutrophils as rapid, NADPH oxidase-independent process involving charge, phagocytosis, phagolysosomal rupture, Ca2+ -flux, hyperpolarization of the mitochondrial membrane, and mitochondrial ROS. Extracellular flow and inhibition experiments suggested that no additional energy from oxidative phosphorylation or glycolysis is required for NET-release. This study suggests a so far unappreciated role for neutrophils in the initial phase of immune responses to alum-containing vaccines in humans and provides novel insights into bioenergetic requirements of NET-formation.
Intravenous (IV) replacement therapy with plasma derived or recombinant factor VIII (FVIII) and factor IX concentrates is the mainstay for treatment of patients with haemophilia A and B. Therefore, the current therapy is particularly dependent on the presence of a secure IV access especially in case of emergency.

A life-threatening bleeding event in an 8-month-old boy is managed by intraosseous (IO) infusion of recombinant FVIII concentrate. No adverse events have been observed 6months after the application, and complete heeling has been reported.

Venous application of factor concentrate remains inevitable in any haemophilic emergency. In case IV access is lacking, an IO institution of factor might be considered. check details To our knowledge, this represents the first reported case of IO application of recombinant FVIII concentrate in a patient with haemophilia.
