Taking medical history, physical examination, and performing some in vivo and in vitro tests are necessary for the diagnosis of allergy. Skin prick test (SPT) is considered as the standard method and first-line approach for the detection of allergic sensitization. Although mainly SPT is used for the detection of allergic sensitization, intradermal skin test (IDST) may be necessary, especially in patients with a negative SPT result. IDST is quite safe; however, is nowadays seldom used for detection of inhalant allergy and its value remains controversial...

Investigations on the photochemical stability of pharmaceutical substances are mandatory in drug development and licensing as photo-induced degradation of an active pharmaceutical ingredient (API) may not only lead to decreased API concentrations but also to toxic or reactive products. Thus, the US Food and Drug Administration (FDA) and the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) issued Guidance for Industry Q1B "Photostability Testing of New Drug Substances and Products" for testing of pure but also packed drugs...

Oral epithelial adhesion to the lamina propria underlies the physiologic function of the oral mucosa and contributes to resisting bacterial invasion, preventing body fluid loss, and maintaining routine chewing; thus, understanding the factors that positively influence oral epithelial adhesion is a research topic of great interest. Rete pegs contribute to oral epithelial adhesion by enlarging the contact areas, whereas integrins are the major molecules that mediate epithelial cell adhesion to the basement membrane...

Oxytocin has emerged as a mediator of endogenous analgesia in behavioral and electrophysiological experiments. In fact, oxytocin receptors (OTRs) in the spinal dorsal horn participate in a selective inhibition of the neuronal activity mediated by Aδ- and C-fibers but not Aβ-fibers. This study shows that OTRs are expressed in the terminal nerve endings and are able to inhibit nociceptive neuronal firing. Indeed, local peripheral oxytocin blocked the first sensorial activity Aδ- and C-fibers recorded in the spinal cord neurons...

Here, we report static and dynamic water motion-induced instability in indium-gallium-zinc-oxide (IGZO) thin-film transistors (TFTs) and its effective suppression with the use of a simple, solution-processed low-k (ε ~ 1.9) fluoroplastic resin (FPR) passivation layer. The liquid-contact electrification effect, in which an undesirable drain current modulation is induced by a dynamic motion of charged liquid such as water, can cause a significant instability in IGZO TFTs. It was found that by adopting a thin (~44 nm) FPR passivation layer for IGZO TFTs, the current modulation induced by the water-contact electrification was greatly reduced in both off- and on-states of the device...

India has a huge patient burden of rheumatic diseases (RDs) including rheumatoid arthritis. The use of biologics has transformed the treatment paradigm for RD; however, biologic treatment-related infections (especially tuberculosis [TB]) are an area of potential concern for TB-endemic nations like India. Anti-tumor necrosis factor (TNF) therapy impairs the physiological TNF-mediated signaling and may cause reactivation and dissemination of latent TB infection (LTBI). Careful screening is, thus, crucial in RD patients who are about to commence anti-TNF treatment...

ETHNOPHARMACOLOGICAL RELEVANCE: Sphagnum mosses and peat could have been utilized as wound dressings for centuries, however reliable data on this subject are ambiguous; sometimes even no distinction between peat moss (Sphagnum spp.) and peat is made or these terms become confused. The first scientific account on surgical use of peat comes from 1882: a peat digger who successfully, by himself and in the way unknown to the then medicine, cured an open fracture of his forearm with peat. The peat, and very soon the peat moss itself (which is the major constituent of peat) drew attention of the 19(th)-century surgeons...

Propolis, a natural compound that can accelerate the wound healing process, is mainly used as ethanolic extract. The extractive solution may also be obtained from the propolis by-product (BP), transforming this waste material into a pharmaceutical active ingredient. Even if propolis does not show toxicity, when used as an extract over harmed skin or mucosa, the present ethanol content may be harmful to the tissue recovering, besides hindering the drug release. This study describes the development of solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) as topical propolis delivery systems and the investigation of their in vitro and in vivo activities...

BACKGROUND: The diagnosis of allergic rhinitis (AR) is based on cutaneous and serological assessment to determine immunoglobulin E (IgE)-mediated disease. However, discrepancies between these tests and nasal provocation exist. Patients diagnosed as non-allergic rhinitis (NAR) but with positive nasal allergen provocation test (NAPT) may represent a local allergic condition or entopy, still suitable to allergy interventions. The objective of this study was to determine the frequency of nasal reactivity toward allergens among AR and NAR patients, and to describe the diagnostic characteristics of NAPT methodologies...

The effect of surfactant type and concentration on a bland soap formulations ability to remove bacteria from hands remains largely unstudied. Several combinations of surfactants and water were combined to test bacterial removal efficacy using a handwashing device (two pieces of pig skin and a mechanical motor) to simulate a handwash. A nalidixic acid resistant, non-pathogenic strain of Escherichia coli (ATCC 11229) was used. Two anionic surfactants, sodium lauryl sulfate and sodium stearoyl lactylate, and two nonionic surfactants, poloxamer 407 and sorbitan monostearate, each in concentrations of 2%, 5%, and 10% were studied...

Increased oxygen consumption by heart and brain mitochondria in the absence of ADP and reduced mitochondrial respiration in the presence of ADP were observed in rats exposed to stress simulated by suspension by the dorsal neck skin fold for 24 h, which attests to uncoupling of substrate oxidation and ATP synthesis and can cause electron drain from the respiratory chain, formation of ROS, and oxidative damage to cell structures. Blockade of inducible NO synthase with aminoguanidine (single intraperitoneal dose of 50 mg/kg before stress exposure) increased coupling of respiration and oxidative phosphorylation in heart and brain mitochondria of rats exposed to immobilization-painful stress, which was especially pronounced in cardiomyocytes...

BACKGROUND: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is often associated with pelvic floor muscle spasm. While pelvic floor physical therapy (PFPT) is effective, some men are unable to resolve their symptoms and have residual trigger points (TPs). TP injection has been used for treatment in several neuromuscular pain syndromes. The objective of this study was to examine the efficacy and side effects of TP injection in men with CP/CPPS and pelvic floor spasm refractory to PT...

Males often fight with rival males for access to females. However, some males display nonfighting tactics such as sneaking, satellite behavior, or female mimicking. When these mating tactics comprise a conditional strategy, they are often thought to be explained by resource holding potential (RHP), that is, nonfighting tactics are displayed by less competitive males who are more likely to lose a fight. The alternative mating tactics, however, can also be explained by life-history theory, which predicts that young males avoid fighting, regardless of their RHP, if it pays off to wait for future reproduction...
