Zhenzhen Hu, Yonggang Wen, Jianfeng Wang, Meng Wang, Richang Hong, Shuicheng Yan
Age estimation based on the human face remains a significant problem in computer vision and pattern recognition. In order to estimate an accurate age or age group of a facial image, most of the existing algorithms require a huge face data set attached with age labels. This imposes a constraint on the utilization of the immensely unlabeled or weakly labeled training data, e.g. the huge amount of human photos in the social networks. These images may provide no age label, but it is easily to derive the age difference for an image pair of the same person...

REVIEW
Meagan Barrett, Minnelly Luu
Atopic dermatitis (AD) is a common inflammatory condition of the skin that is usually seen in childhood, but can onset or persist into adulthood. The characteristic distribution and morphology based on age, chronic relapsing course, and pruritus comprise the clinical criteria used in the diagnosis of AD. However, the numerous morphologies ranging from acute, weeping erythematous papules to chronic lichenified plaques, can be simulated by multiple other conditions, including inflammatory, infectious, neoplastic, and photo-dermatoses...

A2E-laden ARPE-19 cells were exposed to a blue light to induce cytotoxicity, in order to investigate the protective effects of various tinted ophthalmic lenses against photo-induced cytotoxicity in human retinal pigment epithelial (RPE) cells laden with A2E, known to be among the etiologies of age-related macular degeneration (AMD). Different-colored tinted lenses with varying levels of tint and different filtering characteristics, such as polarized, blue-cut, and photochromatic lenses, were placed over the cells, and the protective efficacies thereof were evaluated by lactate dehydrogenase assay...

Rehabilitation research investigating activity participation has been largely conducted in a realist tradition that under-theorises the relationship between persons, technologies, and socio-material places. In this Canadian study we used a post-critical approach to explore activity/setting participation with 19 young people aged 14 to 23 years with complex communication and/or mobility impairments. Methods included integrated photo-elicitation, interviews, and participant observations of community-based activities...

Atmospheric deposition of mercury (Hg) to surface water is one of the dominant sources of Hg in aquatic environments and ultimately drives methylmercury (MeHg) toxin accumulation in fish. It is known that freshly deposited Hg is more readily methylated by microorganisms than aged or preexisting Hg; however the underlying mechanism of this process is unclear. We report that Hg bioavailability is decreased by photochemical reactions between Hg and dissolved organic matter (DOM) in water. Photo-irradiation of Hg-DOM complexes results in loss of Sn(II)-reducible (i...

Objective: That treatment with second-generation antipsychotics (SGAs) causes metabolic side effects and atherosclerosis in patients with schizophrenia and bipolar disorder (BD) is well-known. Increased arterial stiffness is an important marker of arteriosclerosis and has been identified as an independent risk factor for cardiovascular diseases. We measured pulse wave velocity (PWV) as a marker of arteriosclerosis in patients with schizophrenia and BD who use SGAs. Methods: Patients and controls were collected from our psychiatry outpatient clinics or family medicine...

Acrylic copolymers are useful in medical therapeutics. As in dental implants or intraocular lenses, acrylics are present in many medical devices or drug adjuvants. Industrial using of acrylics is still important in painting or textile manufacturing. Scientific research background has proved that acrylic suffer for depolymerized and cross-linking mechanisms under heating and photo-oxidative conditions. Those aging processes could lead to release of unreacted monomers and degradation products. We developed a new RP-HPLC method with good resolution, recovery, linearity, detection and quantification limits that is efficient for acrylic monomers quantification in in vitro and in vivo saline solution matrices...

Purpose: Human chromosomes are protected at their end by a long portion of hexameric tandem repeats, the telomere. In somatic cells, telomere attrition caused by endogenous and exogenous oxidative stress as well as DNA replication can threaten genomic integrity and lead to the deterioration of tissue functions and an age-related physiological decline. The human eye is a complex organ in which cells of different ocular tissues are exposed to photo-oxidation, high mitochondrial metabolic activity, and/or replicative pressure...

OBJECTIVE: Australian Indigenous children experience some of the most substantial health inequalities globally. In this context, research regarding their health and well-being has overemphasised physical illnesses with limited exploration of a diverse range of dimensions and determinants, particularly those based on Indigenous holistic understandings of health and well-being. This deficit-based approach has thus missed many strengths and assets of Indigenous children. This research aimed to gain insight into the perspectives of Indigenous children about their health and well-being in an urban setting in Australia...

The visual recognition memory (VRM) paradigm has been widely used to measure memory during infancy and early childhood; it has also been used to study memory in human and nonhuman adults. Typically, participants are familiarized with stimuli that have no special significance to them. Under these conditions, greater attention to the novel stimulus during the test (i.e., novelty preference) is used as the primary index of memory. Here, we took a novel approach to the VRM paradigm and tested 1-, 2-, and 3-year olds using photos of meaningful stimuli that were drawn from the participants' own environment (e...

Background and study aims: In the Western world, gastric cancer (GC) usually presents at an advanced stage, carrying a high mortality rate. Studies have reported that 14 % to 26 % of GCs are missed at endoscopy up to 3 years before diagnosis. Systematic Alphanumeric Coded Endoscopy (SACE) has been proposed to improve quality of esophagogastroduodenoscopy (EGD) by facilitating a complete examination of the upper gastrointestinal tract. This prospective cross-sectional study was designed to determine the frequency of gastric intraepithelial neoplasia (GIN) by using the SACE approach in cohort of patients from low socioeconomic level...

Polycyclic aromatic hydrocarbons (PAHs) have been reported to absorb ultraviolet (UV) light, resulting in enhanced toxicity. Early developmental stages of bivalves may be particularly susceptible to photo-enhanced toxicity during oil spills. In the current study, toxicity tests were conducted with sperm and three larval ages of the eastern oyster (Crassostrea virginica) to evaluate the photo-enhanced toxicity of low-energy water-accommodated fractions (WAFs) of two weathered Macondo crude oils collected from the Deepwater Horizon incident...

BACKGROUND The person with dementia should be treated as an unique person regarding symptoms directly associated with dementia, such as problems with memory, hallucinations, and delusions, as well as other physical, mental, or neurological deficits. The symptoms not directly typical of dementia, such as musculoskeletal disorders or depression, should be also be considered in order to improve the quality of life of a person with dementia. That is why professional caregivers have to broaden their current knowledge not only of medical symptoms but also of the patient's psychosocial condition and increase their inquisitiveness about the individual condition of the patient...
