The aim of this study is to examine the protective effect of oxyresveratrol (OXY) against isoproterenol-induced myocardial infarction in rats, through routine biochemical parameters and oxidative stress parameters that show heart damage. Oxyresveratrol was administered by oral gavage at doses of 10 and 20 mg/kg, respectively, once a day for 5 days. On the fourth and fifth days, 180 mg/kg isoproterenol was administered intraperitoneally to the OXY treatment group and control groups.

Aim: Impairment of biotin metabolism with the use of isotretinoin and the mucocutaneous side effects observed in patients using isotretinoin suggests that they are a result of decreased enzyme activity. We aimed to determine the pattern of skin and hair changes in patients with acne receiving isotretinoin and how these changes were affected by biotin added to the treatment.
Materials And Methods: Sixty patients were divided into two groups.
We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years, with the intention of providing information to facilitate planning for multi-messenger astronomy with gravitational waves. We estimate the sensitivity of the network to transient gravitational-wave signals for the third (O3), fourth (O4) and fifth observing (O5) runs, including the planned upgrades of the Advanced LIGO and Advanced Virgo detectors. We study the capability of the network to determine the sky location of the source for gravitational-wave signals from the inspiral of binary systems of compact objects, that is binary neutron star, neutron star-black hole, and binary black hole systems.

Methods: In this multicenter study, a total of 15 male and 15 female rats were randomly divided into 3 equal groups according to the oral dose of isotretinoin they were administered: 0 mg/kg/d (group A), 7.5 mg/kg/d (group B), and 15 mg/kg/d (group C).
Introduction: Pemphigus refers to a group of rare autoimmune vesiculobullous diseases with high morbidity and mortality, mainly affecting the skin and the mucosae.
Aim: To evaluate the incidence of pemphigus in the Eastern region of Turkey by analysing the clinical characteristics of the patients including the drugs used in the treatment and their side-effect profiles and dosing schedules, duration of treatment, length of hospital stay, and the characteristics of the lesions.
Material And Methods: The retrospective study included 130 pemphigus patients who were admitted to the in- and out-patient dermatology clinics at the University Medical School between January 2005 and October 2017.
Introduction: Allergic contact dermatitis (ACD) is a form of dermatitis due to type 4 hypersensitivity reaction that occurs when the skin comes into contacts with the topical product. Topical nitrofurazone is a widely used antimicrobial drug in our country which is well known to cause ACD.
Aim: In this study, ACD cases with different clinical features attributed to the use of nitrofurazone were evaluated.
The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source. This source, for the first time, permits tests of strong-field dynamics of compact binaries in the presence of matter. In this Letter, we place constraints on the dipole radiation and possible deviations from GR in the post-Newtonian coefficients that govern the inspiral regime.

Adipose tissue is no longer regarded as a storage site for triglycerides or as a source of free fatty acids but is currently emerging as a key constituent of energy metabolism secreting numerous enzymes, cytokines, growth factors, and hormones.
Aim: To evaluate serum levels of galectin-3 (Gal3), lipocalin-2 (LCN2), retinol binding protein (RBP), and small dense low-density lipoprotein (sdLDL) in patients with hirsutism and patients co-presenting with polycystic ovary syndrome (PCOS) and hirsutism.

Introduction: Genital warts are benign epithelial tumours caused by human papilloma viruses (HPV), and are sexually transmitted. Genotyping of genital HPV bears great clinical significance in terms of treatment planning, follow-up, and prevention strategies.
Aim: To evaluate the distribution of high-risk HPV infection types in patients diagnosed with anogenital warts.
We analyze the impact of a proposed tidal instability coupling p modes and g modes within neutron stars on GW170817. This nonresonant instability transfers energy from the orbit of the binary to internal modes of the stars, accelerating the gravitational-wave driven inspiral. We model the impact of this instability on the phasing of the gravitational wave signal using three parameters per star: an overall amplitude, a saturation frequency, and a spectral index.

Since the analytical performance of HbA1c should be high likewise all laboratory tests, various quality control measures are used. Sigma metrics is one of these measures and it is the combination of bias, precision and total allowable error that ensures a general evaluation of analytical quality.

Although AA is considered to be an autoimmune disease, oxidative stress has been shown to be an important factor in the etiology of AA. Trace elements are highly essential for humans since they form the building blocks of large molecules, function as the cofactors of enzymes, and have some key biological functions.

The detection of this gravitational-wave signal, GW170817, offers a novel opportunity to directly probe the properties of matter at the extreme conditions found in the interior of these stars. The initial, minimal-assumption analysis of the LIGO and Virgo data placed constraints on the tidal effects of the coalescing bodies, which were then translated to constraints on neutron star radii.

A total of 576 1-day-old ROSS 308 broiler chickens were randomly allocated to 4 treatments (8 replicate pens per treatment) in a 2 × 2 factorial arrangement of dietary boric acid (0 and 60 mg/kg) and stocking density (NSD 14 birds/m2 and HSD 22 birds/m2). Basal diets were formulated for starter, grower, and finisher phases.
