RESUMEN
OBJECTIVES: Psychological distress and spiritual well-being (SWB) are directly related to the quality of life in cancer patients. Mindfulness-Based Art Therapy (MBAT) integrates mindfulness practices with art therapy and has shown to decrease distress levels and improve SWB in women with breast cancer. The objective of the study was to identify the effects of a 1-week MBAT intervention on psychological distress and SWB in breast cancer patients undergoing chemotherapy. MATERIALS AND METHODS: This was a single group, pre-test post-test study carried out in a clinical setting. The psycho-oncology assessment questionnaire, Distress Thermometer (DT) and Functional Assessment of Chronic Illness Therapy-SWB Scale 12 (FACIT-SP12) Version 4 were administered before, post1st supervised MBAT session and post 1 week of home practice to breast cancer patients undergoing chemotherapy (n = 30). The MBAT intervention included mindfulness meditation for 15 min and mindful coloring for 30 min daily for 1 week. Data analysis was done using R i386 4.0.3. RESULTS: The median DT score significantly decreased from pre-session to immediate post-session and pre-session to post 1-week session. The median of meaning, peace, and faith subscales of FACIT SP12 scores along with total FACIT SP12 score significantly increased from pre-session to immediate post-session as well as from pre-session to post 1 week. CONCLUSION: One-week MBAT intervention for breast cancer patients undergoing chemotherapy significantly decreased the psychological distress and significantly improved the SWB in terms of meaning, peace, and faith.
RESUMEN
Premature ejaculation (PE) is a common male sexual problem. Various non-pharmacological and pharmacological treatment options are available currently. The importance of yoga in the management of various sexual dysfunctions is increasingly recognized. In this review, we are analyzing the role of yoga in the management of PE. This paper explores the mechanism of yoga practices in the management of PE and the recommended yoga practice for PE. It also discusses the scientific evidence of yoga practices, such as yoga postures (yogasana), breathing practices (pranayama), lock (bandha), gestures (mudra), relaxation, Aum chanting, yoga nidra and meditation with particular reference the management of PE.
RESUMEN
The recent outbreaks of Zika virus (ZIKV) infections and associated microcephaly in newborns has resulted in an unprecedented effort by researchers to target this virus. Significant advances have been made in developing vaccine candidates, treatment strategies and diagnostic assays in a relatively short period of time. Being a preventable disease, the first line of defense against ZIKV would be to vaccinate the highly susceptible target population, especially pregnant women. Along those lines, several vaccine candidates including purified inactivated virus (PIV), live attenuated virus (LAV), virus like particles (VLP), DNA, modified RNA, viral vectors and subunit vaccines have been in the pipeline with several advancing to clinical trials. As the primary objective of Zika vaccination is the prevention of vertical transmission of the virus to the unborn fetus, the safety and efficacy requirements for this vaccine remain unique when compared to other diseases. This review will discuss these recent advances in the field of Zika vaccine development.

Biochemical studies have demonstrated that phosphorylation of lymphocyte cell kinase (p56(lck) ) is crucial for activation of signaling cascades following T cell receptor (TCR) stimulation. However, whether phosphorylation/dephosphorylation of the activating or inhibitory tyrosine residues occurs upon activation is controversial. Recent advances in intracellular staining of phospho-epitopes and cytometric analysis, requiring few cells, have opened up novel avenues for the field of immunological signaling. Here, we assessed p56(lck) phosphorylation, using a multiparameter flow-cytometric based detection method following T cell stimulation. Fixation and permeabilization in conjunction with zenon labeling technology and/or fluorescently labeled antibodies against total p56(lck) or cognate phospho-tyrosine (pY) residues or surface receptors were used for detection purposes. Our observations showed that activation of Jurkat or primary human T cells using H(2) O(2) or TCR-induced stimulation led to simultaneous phosphorylation of the activating tyrosine residue, Y394 and the inhibitory tyrosine residue, Y505 of p56(lck) . This was followed by downstream calcium flux and expression of T cell activation markers; CD69 and CD40 ligand (CD40L). However, the extent of measurable activation readouts depended on the optimal stimulatory conditions (temperature and/or stimuli combinations). Treatment of cells with a p56(lck) -specific inhibitor, PP2, abolished phosphorylation at either residue in a dose-dependent manner. Taken together, these observations show that TCR-induced stimulation of T cells led to simultaneous phosphorylation of p56(lck) residues. This implies that dephosphorylation of Y505 is not crucial for p56(lck) activity. Also, it is clear that cytometric analysis provides for a rapid, sensitive, and quantitative method to supplement biochemical studies on p56(lck) signaling pathways in T cells at single cell level.

Inspired by the anti-human immunodeficiency virus (HIV) activity of analogues of ß-galactosylceramide (GalCer), a set of mono- and di-saccharide fatty acid esters were designed as GalCer mimetics and their binding to the V3 loop peptide of HIV-1 and anti-HIV activity evaluated. 1,1-linked Gal-Man and Glu-Man disaccharides with an ester on the Man subunit bound the V3 loop peptide and inhibited HIV infectivity in single round infection assays with the TZM-bl cell line. IC(50)'s were in the 50 µM range with no toxicity to the cells at concentrations up to 200 µM. These compounds appear to inhibit virus entry at early steps in viral infection since they were inactive if added post viral entry. Although these compounds were found to bind to the V3 loop peptide of gp120, it is not clear that this interaction is responsible for their anti-HIV activity because the relative binding affinity of closely related analogues did not correlate with their antiviral behavior. The low cytotoxicity of these 1,1-linked disaccharide fatty acid esters, combined with the easy accessibility to structurally diverse analogues make these molecules attractive leads for new topical anti-viral agents.
