The vitamin D receptor is found on most cells, including active immune cells, implying that vitamin D has important biological functions beyond calcium metabolism and bone health. Although captive primates should be given a dietary source of vitamin D, under free-living conditions vitamin D is not a required nutrient, but rather is produced in skin when exposed to UV-B light. The circulating level of 25 hydroxyvitamin D (25-OH-D) considered adequate for humans is a topic of current controversy. Levels of circulating 25-OH-D sufficient for good health for macaques and other Old World anthropoids are assumed to be the same as human values, but data from free-living animals are scant...

Breast cancer is the most common cancer in women and is the second most common cause of cancer-related death. Despite the relatively high prevalence of this disease, breast cancer manifestations in the head and neck are relatively rare. Supraclavicular lymphadenopathy and bony metastases to the mandible and maxilla are the most common manifestation of breast cancer in the head and neck. Head and neck metastases are the first presentation of distant disease in approximately one-third of cases. The prognosis of breast cancer with distant metastases to the head and neck is generally poor, and the management of these lesions is controversial...

We proposed that the premise that monogamy is the exemplary form of romantic partnership underlies much theory and research on relationship quality, and we addressed how this bias has prompted methodological issues that make it difficult to effectively address the quality of nonmonogamous relationships. Because the idea that consensually nonmonogamous (CNM) relationships are functional (i.e., satisfying and of high quality) is controversial, we included a basic study to assess, in a variety of ways, the quality of these relationships...

Low-dose chemotherapy has emerged as a new strategy for control of cancer. However, there is a controversy as to whether low-dose chemotherapy is an effective way to manage many human malignancies. To shed light on this controversy, we performed a meta-analysis of relative merits between low-dose and conventional-dose chemotherapy in different carcinomas. Studies published before February 29, 2016 were reviewed for the meta-analysis and selected according to defined criteria. The effect levels of low-dose chemotherapy regarding overall survival (OS), progression-free survival (PFS) and severe adverse events (SAEs) (Grade≥3) were calculated as risk ratios (ORs) or adjusted hazard ratios (HRs)...

Combining with carbon materials is a common and efficient strategy to improve the photocatalytic performance of TiO2. But the fundamental nature of the interfacial microstructures between carbon and TiO2 and how they affect the photocatalysis process remain controversial. In this work, hybrid TiO2@C nanocomposites with different carbon contents are synthesized. It is found that an interfacial disorder region with interfacial Ti-O-C bonds and abundant defects (oxygen vacancies, VO) can be generally formed from the chemical interactions between carbon and Ti-O-Ti skeletons...

1. Introduction Since its introduction in clinical practice in the early 1990's negative pressure wounds therapy (NPWT) has become widely used in the management of complex wounds in both inpatient and outpatient care.(1) NPWT has been described as a effective treatment for wounds of many different aetiologies(2,3) and suggested as a gold standard for treatment of wounds such as open abdominal wounds,(4-6) dehisced sternal wounds following cardiac surgery(7,8) and as a valuable agent in complex non-healing wounds...

PURPOSE: There is still controversy regarding normal and abnormal values of the medial clear space (MCS) of the ankle. The aim of this study was to assess how much different degrees of plantar flexion, with and without stress, influenced the MCS. METHODS: We submitted 30 volunteers to 6 different anteroposterior ankle radiographs in the following positions: neutral, neutral with external rotation stress, physiologic plantar flexion (FPF), physiologic plantar flexion with external rotation stress, maximum plantar flexion (MPF), and maximum plantar flexion with external rotation stress...

AIM: It is well known that consumption of isoflavones reduces the risk of cardiovascular disease. However, the effectiveness of isoflavones in preventing dementia is controversial. A number of intervention studies have produced conflicting results. One possible reason is that the ability to produce equol, a metabolite of a soy isoflavone, differs greatly in individuals. In addition to existing data, we sought to confirm whether an apparent beneficial effect in cognitive function is observed after soy consumption in equol producers compared with non-producers...

Widespread evidence that organic matter exported from terrestrial into aquatic ecosystems supports recipient food webs remains controversial. A pressing question is not only whether high terrestrial support is possible but also what the general conditions are under which it arises. We assemble the largest data set, to date, of the isotopic composition (δ(2)H, δ(13)C, and δ(15)N) of lake zooplankton and the resources at the base of their associated food webs. In total, our data set spans 559 observations across 147 lakes from the boreal to subtropics...

Numerous studies have demonstrated that inflammation contributes to a variety of cancer formation, among them, colitis-associated cancer (CAC) represents a typical inflammation-related cancer. Interleukin 27 (IL-27) has been demonstrated to play an important role in inflammation-related disease. The effect of IL-27 in intestinal inflammation is controversial and its role in CAC is not elucidated yet. In our present study, we found that IL-27 has protective function in murine model of CAC through suppression of inflammatory cytokines in intestinal epithelial cells (IECs)...

Aortic dissection is a life-threatening condition and has one of the highest mortality rates of cardiovascular diseases. It remains a devastating disease; with multiple unanswered questions concerning treatment modalities. The role of thoracic endovascular aortic repair (TEVAR) in these patients; especially those with uncomplicated acute aortic Type B dissections (AAD-B) is especially controversial although it has been shown to have better long-term outcomes compared to medical therapy alone. For those who have TEVAR, up to 60% may develop an acute, transient systemic inflammatory response syndrome that remains vaguely defined...
