Most organisms synchronize to an approximately 24-hour (circadian) rhythm. This study introduces a novel deep learning-powered video tracking method to assess the stability, fragmentation, robustness and synchronization of activity rhythms in . Experimental were distributed into three groups and monitored for synchronization to a 14/10 hours of light/dark to assess acclimation to laboratory conditions.

Instead, the brainstem-diencephalic regions support the wakefulness in amphibians and reptiles. Lastly, mammals developed the telencephalic cortex to attain the highest degree of wakefulness, the cortical wakefulness.

Clinicians need clear and concise assessment instruments to monitor progress recorded in intensive rehabilitation sessions. One such instrument is Manual Muscle Testing (MMT), which, in our view, requires a modified scoring model aimed at improving the assessment process of patients’ motor and functional UE status, and recording their step-by-step-progress, especially if patients undergo a short length of hospitalization (of about 10 therapy days).

Up to the present, an official Romanian version has not been officially available. This study aims to carry out a translation, adaptation, and validation of UEFMA in Romanian, thus giving both patients and medical practitioners the equal opportunity of benefiting from its proficiency.

However, institutionalized elders may suffer reduced exposure to diurnal light, which may impair their circadian rhythms, cognitive performance, and general health status.
Objectives: To analyze the effects of 5 days of morning exposure for 90 min to bright light therapy (BLT) applied to institutionalized elderly subjects with mild/moderate cognitive impairment.
The aim of this study was to compare the availability of diurnal and nocturnal light in two residences for aged persons (R1 and R2, Palma de Mallorca, Illes Balears, Spain). We found that the R1 inmates were exposed to lower amounts of light during waking time and higher amounts during sleeping time. The main traits of the circadian rhythms and the quality of sleep in the inmates of the two residences were found to be positively related to the availability of light during waking time and negatively to the increased light exposure during bed time.

Curiously, their secretion shows parallel and severe age-related reductions. This has promoted many reports for studying the therapeutic supplementation of both hormones in an attempt to avoid or delay the physical, physiological, and psychological decay observed in aged humans and in experimental animals.

Unlabelled: The similar routes of transmission for HIV and HBV place patients with either infection at greater risk for HIV/HBV co-infection.
Aim: To determine the particularities of hepatitis B virus (HBV) coinfection in pregnant women infected with human immunodeficiency virus (HIV) and its influence on pregnancy.
Methods: Retrospective study of 74 HIV-infected women monitored during pregnancy in the Iasi Regional HIV/AIDS Center (Romania) from 2010 to 2013.
Purpose: To analyze the role of radiation therapy (RT) on the adverse prognostic influence of cyclooxygenase-2 (COX-2) expression on Reed-Sternberg (RS) cells, in the setting of early Hodgkin lymphoma (HL) treated with ABVD (adriamycin, vinblastine, bleomycin, dacarbazine).
Methods And Materials: In the present study we retrospectively investigated the prognostic value of COX-2 expression in a large (n=143), uniformly treated early HL population from the Spanish Network of HL using tissue microarrays. Univariate and multivariate analyses were done, including the most recognized clinical variables and the potential role of administration of adjuvant RT.

Aim: The paper aims to outline the naïve HIV-positive patient's profile, in terms of feelings and emotions post-diagnosis.
Material And Methods: The evaluation took place from January 2011 to December 2013 in the Psycho-social Assistance Office of the "Sfânta Parascheva" Infectious Diseases Hospital in Iaşi. We evaluated 146 patients newly diagnosed with HIV infection, both in terms of immunological and virusological and from a psychological perspective, using the Hamilton Anxiety Scale (HAMA), Beck Depression Inventory II (BDI) and the clinical interview.

Aim: The HIV infected population in Romania is at an age when engaging in a serious relationship is more and more an issue. Dyadic adjustment is the process which most couples go through, in their attempt to form a steady relationship. It is represented by important changes that appear in one's perception of himself and the significant other.

Birds also show asymmetric sleep, probably to avoid predation. The variable function of asymmetric sleep suggests a general capability for independence between brain hemispheres.

Unlabelled: Quality of life in relation to health is a consequence of disease and treatment on the patient's perception of his ability to have a full and useful life. Due to its nature, the quality of life is a multidimensional and subjective construct, based on the patient's experience. We operationalized the quality of life using the following parameters: CD4 count and HIV viral levels in the patient's blood, the number of days of hospitalization, number of antiretroviral plans, types of side effects and their frequency, psychological issues (anxiety, depression, and neurotic tendencies).

Thus far, most hypotheses on the evolutionary origin of sleep only addressed the probable origin of its main states, REM and NREM. Our article presents the origin of the whole continuum of mammalian vigilance states including waking, sleep and hibernation and the causes of the alternation NREM-REM in a sleeping episode. We propose: (1) the active state of reptiles is a form of subcortical waking, without homology with the cortical waking of mammals; (2) reptilian waking gave origin to mammalian sleep; (3) reptilian basking behaviour evolved into NREM; (4) post-basking risk assessment behaviour, with motor suspension, head dipping movements, eye scanning and stretch attending postures, evolved into phasic REM; (5) post-basking, goal directed behaviour evolved into tonic REM and (6) nocturnal rest evolved to shallow torpor.
