Background: Oral health is important for maintaining general health among the elderly. However, a longitudinal association between poor oral health and general health has not been reported. We investigated whether poor oral status can predict physical weakening (physical frailty, sarcopenia, subsequent disability) and identified the longitudinal impact of the accumulated poor oral health (i.e., oral frailty) on adverse health outcomes, including mortality. Methods: A total of 2,011 elderly individuals (aged ≥65 years) participated in the baseline survey of the Kashiwa study in 2012...

Alzheimer's disease (AD) involves dementia conceivably arising from integrated inflammatory processes, amyloidogenesis and neuronal apoptosis. Glutamate can also cause neuronal death via excitotoxicity and this is similarly implicated in some neurological diseases. The aim was to examine treatment with in vitro generated pro-inflammatory protein S100A9 aggregate species alone or with glutamate antibodies (Glu-Abs) on Morris water maze (MWM) spatial learning and memory performance in 12-month old mice. Amino acid and monoamine cerebral neurotransmitter metabolic changes were concurrently monitored...

Background: Recent studies confirmed that immunotherapy showed prominent efficacy in non-small cell lung cancer (NSCLC). Cancer stem cells/cancer initiating cells are resistant to anticancer treatment. The purpose of the study was to analyze the correlation of cancer stem cells/cancer initiating cells and tumor-infiltrating immune cells in NSCLC. Methods: CD133, octamer 4 (OCT-4), CD8, CD56, human leukocyte antigen (HLA) class I and programmed death ligand-1 (PD-L1) were assessed in 172 resected NSCLC samples...

BACKGROUND: Breast cancer is a leading cause of death in the United States. Continuing medical education programs such as the American Board of Internal Medicine's Maintenance of Certification (MOC) program can increase early detection of cancers by educating physicians about the benefits of screening. Did the imposition of American Board of Internal Medicine's MOC requirement affect guideline-compliant mammography screening? METHOD: To address this question, we took advantage of a natural experiment that occurred when one group of general internists was required to complete MOC by 2001 because they initially certified in 1991 (MOC required) and another group was grandfathered out of this requirement because they initially certified in 1989 (MOC grandfathers)...

Euthanasia was decriminalized in Quebec in December 2015, and Canada-wide in June 2016. Both the Provincial and Federal legislation have limited the right to medical assistance in dying (MAID) to end-of-life cases; which makes MAID inaccessible to most patients solely suffering from psychiatric illness. While some end-stage anorexia nervosa or elderly patients may meet the end-of-life criterion because of their medical comorbidities or their age (Kelly et al., 2003), repeated suicide attempts or psychotic disorganization would not qualify since they would not be seen as elements of an illness leading to a foreseeable "natural death" (Canada, 2016)...

Cancer continues to be one in all the leading reasons for death worldwide. The mean cancer survival through standard therapeutic strategies has not been significantly improved over the past few decades. Hence, alternate remedies are needed to treat this terrible disease. Recently, natural compounds present in the plants, i.e. phytochemicals have been widely exploited for their anticancer potential. Phytochemicals may exhibit their anticancer activity through targeting different cancer cell signaling pathways, promoting cell cycle arrest and apoptosis, regulating antioxidant status and detoxification...

In this article, I do not intend to present the many and well-known treatments for relieving pain and distress symptoms of the physical body, damaged by terminal diseases, such as cancer, AIDS, multiple sclerosis. In this article, I'd rather focus my attention on clinical hypnosis for subjects who, freed from physical pain, thanks to palliative care, are open to receiving comfort and support for their psychological and spiritual suffering. The intent of this article is to express how clinical hypnosis can harmoniously integrate psychological and spiritual aspects so that the terminal patient can make peace with his/her past, with the people who have hurt him/her, and with the people who will suffer because of his/her death...

Life tables provide a means of measuring the schedules of birth and death from populations over time. They also can be used to quantify the sources and rates of mortality in populations, which has a variety of applications in ecology, including agricultural ecosystems. Horizontal, or cohort-based, life tables provide for the most direct and accurate method of quantifying vital population rates because they follow a group of individuals in a population from birth to death. Here, protocols are presented for conducting and analyzing cohort-based life tables in the field that takes advantage of the sessile nature of the immature life stages of a global insect pest, Bemisia tabaci...

Macrophages highly express epidermal fatty acid-binding protein and adipose fatty acid-binding protein. They actively uptake saturated and unsaturated fatty acids, which might play a critical role in regulating their immune functions. Numerous studies have shown that various fatty acids, saturated or unsaturated, may possess different impacts on cell growth and function. However, the approaches used for fatty acid preparation vary, which may lead to non-physiological results. Serum albumin, a natural carrier for fatty acids in mammalian peripheral blood, is recommended for forming a conjugate complex with the sodium salt of fatty acids to study fatty acid function in mammalian cells, thus minimizing the toxicity of fatty acid soap...

Alzheimer's disease (AD) is a debilitating neurodegenerative disease in which accumulation of toxic amyloid-β42 (Aβ42) peptides leads to synaptic degeneration, inflammation, neuronal death, and learning deficits. Humans cannot regenerate lost neurons in the case of AD in part due to impaired proliferative capacity of the neural stem/progenitor cells (NSPCs) and reduced neurogenesis. Therefore, efficient regenerative therapies should also enhance the proliferation and neurogenic capacity of NSPCs. Zebrafish (Danio rerio) is a regenerative organism, and we can learn the basic molecular programs with which we could design therapeutic approaches to tackle AD...

Recent literature strongly challenged indications to perform preventive surgery in unruptured AVM. claiming that invasive AVM treatment is associated with a significant risk of complications and thus conservative management may be a preferable alternative in many patients. On the other hand, the recent improvement of surgical instrumentation and treatment strategies (both surgical and interventional) yielded much better outcomes than those achieved only a decade ago. Therefore, even among the specialists, a wide variety of opinions, concerning the treatment of unruptured AVM, can be found...

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common type of dementia in elderly ( >65years of age). Excessive extra cellular deposits of amyloid beta (Aβ) are a pathological feature of AD. Aβ can cause cell death through oxidative damage; recent studies have implicated opening of mPTP as a detrimental event in AD-related mitochondrial dysfunctions. Over the past few years, natural compounds with antioxidant properties have shown promise for intervention in AD.

BACKGROUND: Many multi-center epidemiological studies have robustly examined the acute health effects of exposure to low concentrations of fine particulate matter (PM2.5) on cardiovascular mortality in developed counties. However, data limitations have resulted in few related studies being conducted in developing counties with high levels of PM2.5 exposure. In recent years, people in China with a heavy cardiovascular disease burden have been exposed to particularly high levels of PM2...

Metabolic gene clusters (MGCs) have provided some of the earliest glimpses at the biochemical machinery of yeast and filamentous fungi. MGCs encode diverse genetic mechanisms for nutrient acquisition and the synthesis/degradation of essential and adaptive metabolites. Beyond encoding the enzymes performing these discrete anabolic or catabolic processes, MGCs may encode a range of mechanisms that enable their persistence as genetic consortia; these include enzymatic mechanisms to protect their host fungi from their inherent toxicities, and integrated regulatory machinery...

In cranial firearm trauma, where soft tissues have decomposed, determining the manner of death can pose difficultly for a forensic anthropologist. Detailed analysis of skeletal wounds may lead to reconstruction of the events surrounding death, however considerable research has been conducted on soft tissue details and less has focused on skeletal wounds alone. Macroscopic descriptive observations were carried out on thirteen skulls from the Hamman-Todd Human Osteological Collection at the Cleveland Museum of Natural History, Ohio which had documented cranial projectile trauma to analyse wound location, shape, size, beveling and projectile paths...

Certain low pathogenic avian influenza viruses can mutate to highly pathogenic viruses when they circulate in domestic poultry, at which point they can cause devastating poultry diseases and severe economic damage. The H7N9 influenza viruses that emerged in 2013 in China had caused severe human infections and deaths. However, these viruses were nonlethal in poultry. It is unknown whether the H7N9 viruses can acquire additional mutations during their circulation in nature and become lethal to poultry and more dangerous for humans...

OBJECTIVE: Infantile-onset spinal muscular atrophy (SMA) is the most common genetic cause of infant mortality, typically resulting in death prior to age 2. Clinical trials in this population require an understanding of disease progression and identification of meaningful biomarkers to hasten therapeutic development and predict outcomes. METHODS: A longitudinal, multi-center, prospective natural history study enrolled 26 SMA infants, and 27 control infants less than six months of age...

Influenza virus of different subtypes H1N1, H2N2, H3N2 and H5N1 cause many human pandemic deaths and threatening the people worldwide. The Hemagglutinin (HA) protein mediates viral attachment to host receptors act as an attractive target. The sixteen natural compounds have been chosen to target the HA protein. Molecular docking studies have been performed to find binding affinity of the compounds. Out of the sixteen, three compounds CI, CII and CIII found to posses a higher binding affinity. The molecular dynamics (MD) simulation has been performed to study the structural, dynamical properties for the nine different complexes CI, CII, CIII bound with H1, H2, H3 proteins and the results were compared...

BACKGROUND: Hepatocellular carcinoma (HCC) causes over 800,000 deaths worldwide annually, mainly in low income countries, and incidence is rising rapidly in the developed world with the spread of hepatitis B (HBV) and C (HCV) viruses. Natural Killer (NK) cells protect against viral infections and tumours by killing abnormal cells recognised by Killer-cell Immunoglobulin-like Receptors (KIR). Thus genes and haplotypes encoding these receptors may be important in determining both outcome of initial hepatitis infection and subsequent chronic liver disease and tumour formation...
