AIM: Decreased level of serum calcium was commonly seen in critical illness. Hypocalcemia was significantly more frequent in patients with severe form of acute pancreatitis (AP), and a negative correlation was observed between endotoxemia and serum calcium in AP. AP patients with persistent organ failure (POF) show an extremely high mortality. The association underlying calcium and POF in AP has not been characterized. METHODS: We conducted a retrospective cohort study of adult patients who presented within 72hours from symptom onset of AP at our center between January 2014 and May 2015...

Knowledge of an individual's skin condition is important for pressure ulcer prevention. Detecting early changes in skin through perfusion, oxygen saturation values, and pressure on tissue and subsequent therapeutic intervention could increase patients' quality of life drastically. However, most existing sensing options create additional risk of ulcer development due to further pressure on and chafing of the skin. Here, as a first component, we present a flexible, photonic textile-based sensor for the continuous monitoring of the heartbeat and blood flow...

Premature ovarian failure (POF) is a kind of gynecological disease that causes amenorrhea, infertility, menopause and urogenital symptoms. Currently hormone replacement therapy (HRT) is the most popular choice for women with POF to get rid of menopausal syndrome. However, as the popularization of Chinese herbs made Chinese medicine (CM) shine new lights, physicians are able to treat POF with both meno-herbs and integrated therapy. HRT has its own indications and contraindications. For example, unexplained vaginal bleeding, acute liver damage, liver dysfunction, vascular embolization, and breast cancer are all contraindications of HRT, and CM is taken by more physicians as an adjuvant therapy...

The common snook, Centropomus undecimalis, was induced to ovulate using a time-release, GnRH analogue. Ovulation occurred the afternoon or evening the day after hormone administration. The time of ovulation was established within half an hour. At ovulation, three fish per time-group were divided into 0, 6, 12, 18 hr and one thru five days post-ovulation to study changes in the postovulatory follicle complex (POC). Histology of the ovaries revealed changes in the POC, postovulatory follicle (POF) and oocyte atresia through five days post-ovulation...

REVIEW
Beata Komorowska
Premature ovarian failure (POF), also termed as primary ovarian insufficiency (POI), is a highly heterogenous condition affecting 0.5-3.0% of women in childbearing age. These young women comprise quite a formidable group with unique physical and psychological needs that require special attention. Premature ovarian senescence (POS) in all of its forms evolves insidiously as a basically asymptomatic process, leading to complete loss of ovarian function, and POI/POF diagnoses are currently made at relatively late stages...

Chuanxin Teng, Ning Jing, Fangda Yu, Yue Ding, Jie Zheng
We propose a plastic optical fiber (POF) with a multi-notched structure as a long-period grating for refractive index (RI) sensing. A new approach to modify the structure of POFs with enhanced RI sensitivity was carried out. The multi-notched structure was made on the surface of the fiber by pressing a thread rod against the POF. The RI sensing performances for straight and macro-bending (U-shaped) POFs with this structure were studied. It is found that the POF probes with straight multi-notched structures were not sensitive enough for RI measurements...

This work was designed to study whether viscous media can improve the in vitro sperm functionality in pigs by using methylcellulose as a thickener. Viscosity of porcine oviductal fluid (POF) was compared with culture medium (Tyrode's) supplemented with methylcellulose (MET 0, 0.5 and 1% w/v). Spermatozoa were incubated in the different media (0, 1 and 2 h) and sperm motion parameters, lipid membrane disorder, plasma membrane integrity and reactive oxygen species (ROS) formation were assessed. Fertilization results were assessed i) preincubating spermatozoa in the viscous media followed by gamete coculture in a non-viscous medium; and ii) gamete coculture in the viscous media...

The origin and function of exaggerated traits exhibited by a great number of species with sexual dimorphism remain largely unexplored. The usual model considered as the evolutionary mechanism for the development of these structures is sexual selection. The nature of growth of the postocular flange (POF) in three species of the dobsonfly genus Platyneuromus (Megaloptera, Corydalidae, Corydalinae) is analyzed to explore sexual size dimorphism and allometric scaling. Results involve positive allometry of POF in males of two species, and negative allometry in males of one species, in general with a female-biased sexual dimorphism...

Parabens are widely used preservatives in basic necessities such as cosmetic and pharmaceutical products. In previous studies, xenoestrogenic actions of parabens were reported in an immature rat model and a rat pituitary cell line (GH3 cells). The relationship between parabens and ovarian failure has not been described. In the present study, the influence of parabens on ovarian folliculogenesis and steroidogenesis was investigated. A disruptor of ovarian small pre-antral follicles, 4-vinylcyclohexene diepoxide (VCD, 40 mg/kg), was used to induce premature ovarian failure (POF)...

A novel solid-phase microextraction (SPME) fiber was fabricated by a porous aromatic framework 48 (PAF-48)/gel hybrid material through a sol-gel process. PAF-48 is a porous organic framework (POF) material that was polymerized from 1,3,5-triphenylbenzene. The uniform pore structure, high surface area, continuous conjugate network, and hydrophobicity make PAF-48 expected to have special abilities to absorb and extract styrene as well as some other harmful volatile aromatic compounds (VACs). The PAF-48/gel-coated fiber was explored for the extraction of styrene and six VACs (benzene, toluene, ethylbenzene, and xylenes) from aqueous food simulants followed by gas chromatography (GC) separation...

This study aims to investigate the effect as well as mechanism of ginsenoside Rg1 (Rg1) on premature ovarian failure (POF) induced by d-galactose (d-gal) in mice. C57BL/6 female mice were divided into four groups randomly, which were the saline group, the d-gal group, the d-gal + Rg1 group, and the Rg1 group. Body weight was recorded. Overall ovarian function including estrous cycles, sex hormone secretion, ovarian follicle development, and ovarian morphology was analyzed by H&E staining and ELISA. Effect of Rg1 on aging was determined by analyzing the activities of oxidation-associated biomarkers, pro-inflammatory cytokine secretion, expression of senescence-associated proteins, and fertility...

This paper proposes the strategy of fabricating an all fiber wide-range displacement sensor based on the macro-bend coupling effect which causes power transmission between two twisted bending plastic optical fibers (POF), where the coupling power changes with the bending radius of the fibers. For the sensor, a structure of two twisted plastic fibers is designed with the experimental platform that we constructed. The influence of external temperature and displacement speed shifts are reported. The displacement sensor performance is the sensor test at different temperatures and speeds...

BACKGROUND: Young female patients who receive chemotherapy frequently face premature ovarian failure (POF). The therapeutic potential of stem cells in these patients has been explored in stem cells derived from different sources. However, many of these types of stem cells are either difficult to obtain or obtaining them involves invasive procedures. Here, we show that menstrual-derived stem cells (MenSCs) are easy to access and exhibit mesenchymal stem cell-like properties. MenSCs are therefore a novel source of stem cells that can be used for tissue repair...

The objective of the present study was to observe the curative effect and mechanism of melatonin for suppression of premature ovarian failure (POF). From December 2014 to June 2015, 128 patients were consecutively diagnosed with POF in the Department of Gynaecology and Obstetrics. The patients were randomly divided into the experimental and control groups. The experimental group received melatonin tablets (1-3 mg/day), while the control group received placebo tablets. The levels of six sex hormones, percentage of T lymphocytes in the G1/M phase, and levels of reactive oxygen species (ROS) were determined at four different time-points (1 day before treatment, and at 1, 3 and 6 months after treatment) in both groups...
