Due to its remote and isolated location, Antarctica is home to a unique diversity of species. The harsh conditions have shaped a primarily highly adapted endemic fauna. This includes the notothenioid family Channichthyidae. Their exceptional physiological adaptations have made this family of icefish the focus of many studies. However, studies on their ecology, especially on their parasite fauna, are comparatively rare. Parasites, directly linked to the food chain, can function as biological indicators and provide valuable information on host ecology (e...

Eclampsia is a common problem in pregnancy in Bangladesh. It is a severe form of preeclampsia which affects 5 to 7% of pregnancies is a significant cause of maternal & neonatal morbidity & mortality. Pre-eclampsia when complicated with generalized tonic-clonic convulsions and/or coma is called eclampsia. The term eclampsia is derived from a Greek word, meaning "like a flash of lightening". It may occur quite abruptly, without any warning manifestations. Eclampsia is a major cause of maternal mortality & morbidity as well as foetal loss worldwide, particularly in the third world...

PURPOSE OF REVIEW: Colourism, a form of prejudice and discrimination based solely upon skin colour, stands to jeopardize the physical health, wellbeing and life chances of adolescents of colour, globally. RECENT FINDINGS: Research shows that adolescents can experience colourism at school and college, in the criminal justice system, at work and in the media they consume. It is therefore unsurprising that adolescents of colour often express a desire for lighter skin tones and/or are dissatisfied with their skin tone...

Port-wine stains (PWS) affect 0.3 to 0.5% of newborns and pulsed dye laser (PDL) remains the treatment of choice. However, no reliable study regarding the benefits of more frequent has been conducted. We designed the present study to evaluate whether more frequent PDL treatments in infantile patients would achieve further lightening of erythema. We prospectively investigated 20 infants with PWS. Two adjacent sites were both treated for a 12-week duration and randomly allocated to be treated for seven sessions at 2-week intervals or three sessions at 6-week intervals...

Saline water has been proposed as a solution to partially cover plant water demands due to scarcity of irrigation water in hot arid areas. Lavender ( Lavandula angustifolia Mill.) plants were grown hydroponically under salinity (0-25-50-100 mM NaCl). The overcome of salinity stress was examined by K, Zn, and Si foliar application for the plant physiological and biochemical characteristics. The present study indicated that high (100 mM NaCl) salinity decreased plant growth, content of phenolics and antioxidant status and essential oil (EO) yield, while low-moderate salinity levels maintained the volatile oil profile in lavender...

The aim of this study was the evaluation of activities of versatile peroxidase (VP) in cultures of Clonostachys sp. ( Gliocladium sp.) strains during biotransformation of 0.2% alkali lignin (AL). The principal component analysis (PCA) method was applied to determine the main factors and correlation between biotransformation of 0.2% AL, activity of VPs, pH value, and Clonostachys sp. strains. The biotransformation of 0.2% AL in cultures of microscopic fungi included decolorization (medium lightening) and colorization (darkening of the medium)...

Many species alter skin color to varying degrees and by different mechanisms. Here, we show that some crocodylians modify skin coloration in response to changing light and environmental conditions. Within the Family, Crocodylidae, all members of the genus Crocodylus lightened substantially when transitioned from dark enclosure to white enclosures, whereas Mecistops and Osteolaemus showed little/no change. The two members of the Family Gavialidae showed an opposite response, lightening under darker conditions, while all member of the Family Alligatoridae showed no changes...

In this study, we explored the neuroprotective effects of docosahexaenoic acid (DHA) in traumatic brain injury (TBI) models. In this study, we first confirmed that DHA was neuroprotective against TBI via the NSS test and Morris water maze experiment. Western blot was conducted to identify the expression of Bax, caspase-3, and Bcl-2. And the cell apoptosis of the TBI models was validated by TUNEL staining. Relationships between nuclear factor erythroid 2-related factor 2-antioxidant response element (Nrf2-ARE) pathway-related genes and DHA were explored by RT-PCR and Western blot...

BACKGROUND: Diabetes mellitus is a chronic disease with a high prevalence across the world as well as in South Korea. Most cases of diabetes can be adequately managed at physician offices, but many diabetes patients receive outpatient care at hospitals. This study examines the relationship between supplementary private health insurance (SPHI) ownership and the use of hospitals among diabetes outpatients within the universal public health insurance scheme. METHODS: Data from the 2011 Korea Health Panel, a nationally representative sample of Korean individuals, was used...

CD8+ cytolytic T lymphocytes are essential players of anti-tumor immune responses. On tumors, they recognize peptides of about 8-to-10 amino acids that generally result from the degradation of cellular proteins by the proteasome. Until a decade ago, these peptides were thought to solely correspond to linear fragments of proteins that were liberated after the hydrolysis of the peptide bonds located at their extremities. However, several examples of peptides containing two fragments originally distant in the protein sequence challenged this concept and demonstrated that proteasome could also splice peptides together by creating a new peptide bond between two distant fragments...

16S ribosomal RNA gene sequences are characteristically used as gold-standard genetic marker for the determination of bacterial and/or archaeal biodiversity, and community profiling of environmental samples. The 16S rRNA amplicon analysis till-date is taken as a standard method for investigation and identification of uncultivable bacteria in microbial diversity studies. The accuracy of these analyses strongly depends upon the choice of primers. It is presumed that these primers do not participate in non-specific amplifications...

Despite its extensive use, the traditional 4f Vander Lugt Correlator optical setup can be further simplified. We propose a lightweight correlation scheme where the decision is taken in the Fourier plane. For this purpose, the Fourier plane is adapted and used as a decision plane. Then, the offline phase and the decision metric are re-examined in order to keep a reasonable recognition rate. The benefits of the proposed approach are numerous: (1) it overcomes the constraints related to the use of a second lens; (2) the optical correlation setup is simplified; (3) the multiplication with the correlation filter can be done digitally, which offers a higher adaptability according to the application...

In this laboratory study, a composite resin was stained to a visibly discernible level using both coffee and red wine over 14 days (change was considered clinically noticeable and significant when ΔEab *≥2.7). Color change was measured at one, three, seven, and 14 days of staining. Although the nature of color change was different for the two staining solutions, the overall degree of staining (ΔEab *) rendered by either coffee or wine at each time interval was not significantly different ( p≥0.05). Four whitening protocols were applied to stained composites...

Here, we present a case of pituitary adenoma producing adrenocorticotropic hormone (ACTH) in a 19-year-old woman. The patient was admitted to neurosurgery clinic because of a headache and decreased visual acuity. Transsphenoidal resection was performed. Microscopic examination of the tumor revealed signet-ring-like cell areas intermixed with conventional pituitary adenoma cells. Both populations of tumor cells showed immunoreactivity for chromogranin, synaptophysin, and ACTH. To date, there have been 3 reports of pituitary adenoma with signet-ring-like changes...

ADAMTS3 is a member of procollagen N-proteinase subfamily of ADAMTS (a disintegrin and metalloproteinase with thrombospondin motifs) gene family. It has an important function in the procollagen maturation process. The removal of N-peptidases is required for the accurate processing of fibrillar collagens. Otherwise, several disorders can occur that is related with the collagenous tissues. ADAMTS3 mainly maturates type II collagen molecule which is the main component of the bone and cartilage. There are several expression studies about ADAMTS3 gene however its transcriptional regulation has not been lightened up, yet...

Although cooperatively breeding vertebrates occur disproportionately in unpredictable environments, the underlying mechanism shaping this biogeographic pattern remains unclear. Cooperative breeding may buffer against harsh conditions (hard life hypothesis), or additionally allow for sustained breeding under benign conditions (temporal variability hypothesis). To distinguish between the hard life and temporal variability hypotheses, we investigated whether the number of alloparents at a nest increased reproductive success or load-lightening in superb starlings ( Lamprotornis superbus ), and whether these two types of benefits varied in harsh and benign years...

A mother brought her 8-year-old daughter to our office for evaluation of vitiligo "down there". The skin eruption first appeared on her vulva a year earlier and was intermittently pruritic. The lesions were initially smaller and red, but had since lightened in color, coalesced, and had begun to spread to the perianal area. The patient's mother had received a call from her daughter's teacher who observed that her daughter was scratching the area and might be masturbating in class. WHAT IS YOUR DIAGNOSIS? HOW WOULD YOU TREAT THIS PATIENT?...

Electronic supporting information (ESI) occupies a fundamental position in the way scientists report their work. It is a key element in lightening the writing of the core manuscript and makes concise communication easier for the authors. Computational chemistry, as all fields related to structural studies of molecules, tends to generate huge amounts of data that should be inserted in the ESI. ESI reports originating from computational chemistry works generally reach tens of sheets long and include 3D depictions, coordinates, energies, and other characteristics of the structures involved in the molecular process understudy...

UVA comprises more than 90% of the solar UV radiation reaching the Earth. Artificial lightening lamps have also been reported to emit significant amounts of UVA. Exposure to UVA has been associated with dermatological disorders including skin cancer. At the molecular level, UVA damages different cellular biomolecules and triggers inflammatory responses. The current study was devoted to investigate the potential protective effect of L-carnitine against UVA-induced skin tissue injury using rats as a mammalian model...
