Repetitive transcranial magnetic stimulation (rTMS) is a promising method for use in the clinical field, as it can induce modulation of cortical excitability. Generally, rTMS inhibits the motor cortex when delivered at less than 1Hz. However, it has been indicated that a facilitative effect is induced by 1Hz rTMS, depending on the stimulation parameters and the individual. Therefore, the aim of this study was to investigate the features of the subject that could affect the 1Hz rTMS effect when rTMS stimulus conditions change...

Papillon-Lefèvre syndrome (PLS) is a rare autosomal recessive disorder of keratinization associated with palmoplantar keratoderma and severe periodontitis resulting in complete edentulism in late adolescence. The pathognomonic dental features of PLS are pathologic migration, hypermobility, and exfoliation of the teeth without any signs of root resorption. It has been suggested that an effective way to treat PLS patients presenting early in the disease progression is extraction of the erupted primary dentition or hopeless permanent teeth followed by antibiotic coverage with periodontal therapy for the remaining teeth...

BACKGROUND: The longitudinal effects of peritoneal dialysis (PD) peritonitis on small solute clearance and ultrafiltration are controversial. MATERIALS AND METHODS: We identified 27 patients with PD peritonitis over a 4-year period at a tertiary hospital. Adequacy tests at an "early" (1 - 3 months), "intermediate" (6 ± 2 months), and a "late" (12 ± 2 months) time period after the episode were compared with a pre-peritonitis baseline. The effect of time on serum albumin, weekly creatinine clearance, Kt/V, and net fluid volume removal was assessed...

α-Glucosidase inhibitor was a new type of antidiabetics which was developed in the late 1970s. By reducing the postprandial blood sugar concentration, it could effectively control the blood sugar levels, thereby reducing the occurrence of diabetic complications. Studies have shown that plant secondary metabolites have important biological functions such as hpyerglycemic, anti-hyperlipidemia, immunomodulatory, and antitumor effects. In this paper, the sources of plant secondary metabolites which are able to inhibit α-glucosidase and their inhibition mechanism would be reviewed to provide references for seeking more safe and efficient plant secondary metabolites of α-glucosidase inhibitors...

BACKGROUND: The zinc-finger transcription factor Nolz1 regulates spinal cord neuron development by interacting with the transcription factors Isl1, Lim1 and Lim3, which are also important for photoreceptors, horizontal and bipolar cells during retinal development. We therefore studied Nolz1 during retinal development. RESULTS: Nolz1 expression was seen in two waves during development: one early (peak at embryonic day 3-4.5) in retinal progenitors and one late (embryonic day 8) in newly differentiated cells in the inner nuclear layer...

OBJECTIVES: In Greece, during the late 19th and early 20th century, the rural population adopted a more or less urban lifestyle. Furthermore, the first half of the 20th century finds Greece involved in five major wars, including a civil war, and consequent financial deprivation. This study investigates how the socioeconomic changes in Greece, during this period of time, have affected the stature of its population. METHODS: The Athens collection constitutes our sample with 189 adult individuals (104 males and 85 females)...

PURPOSE OF REVIEW: The purpose of this paper is to provide a review of the use of ketamine as an antidepressant for treatment-resistant depression (TRD) in the geriatric population. Available treatment options for late-life treatment-resistant depression are limited and include electroconvulsive therapy and transcranial magnetic stimulation as well as possible pharmacologic augmentation. Ketamine has been shown to be a promising treatment in TRD; however, data regarding the use of ketamine in the elderly includes only five case reports...

UV-B acclimation effects and UV-B damage repair induced by a 632.8-nm He-Ne laser were investigated in Arabidopsis thaliana plants in response to supplementary UV-B stress. There was an increasing trend in growth parameters in the combination-treated plants with He-Ne laser and UV-B light compared to those stressed with enhanced UV-B light alone during different developmental stages of plants. The photosynthetic efficiency (Pn) and survival rates of seedlings were significantly higher in the combination treatments than UV-B stress alone...

Long-term potentiation (LTP) is the persistent increase in the strength of the synapses. However, the neural networks would become saturated if there is only synaptic strenghthening. Synaptic weakening could be facilitated by active processes like long-term depression (LTD). Molecular mechanisms that facilitate the weakening of synapses and thereby stabilize the synapses are also important in learning and memory. Here we show that blockade of dopaminergic D4 receptors (D4R) promoted the formation of late-LTP and transformed early-LTP into late-LTP...

Intracellular pathogenic microorganisms and toxins exploit host cell mechanisms to enter, exert their deleterious effects as well as hijack host nutrition for their development. A potential approach to treat multiple pathogen infections and that should not induce drug resistance is the use of small molecules that target host components. We identified the compound 1-adamantyl (5-bromo-2-methoxybenzyl) amine (ABMA) from a cell-based high throughput screening for its capacity to protect human cells and mice against ricin toxin without toxicity...

Cell rounding is a hallmark of the cytopathic effect induced by cytomegaloviruses. By screening a panel of deletion mutants of mouse cytomegalovirus (MCMV) a mutant was identified that did not elicit cell rounding and lacked the ability to form typical plaques. Altered cell morphology was assigned to the viral M25 gene. We detected an early 2.8 kb M25 mRNA directing the synthesis of a 105 kDa M25 protein, and confirmed that a late 3.1 kb mRNA encodes a 130 kDa M25 tegument protein. Virions lacking the M25 tegument protein were of smaller size because the tegument layer between capsid and viral envelope was reduced...

Previous research suggests that electrophysiological correlates of performance monitoring, in particular the error-related negativity (ERN), vary according to psychopathology and context factors. The present study examined the effect of social context on behavioral and electrophysiological correlates of performance monitoring in healthy adult subjects and in patients with social anxiety disorder (SAD). Participants performed two runs of a Go/NoGo flanker task in different social conditions: in the observation condition, they were observed by a confederate while performing the task, whereas there was no observation in the control condition...

REVIEW
Mark J Kearns, Keith R Walley
Cardiac tamponade is a medical emergency that can be readily reversed with timely recognition and appropriate intervention. The clinical diagnosis of cardiac tamponade requires synthesis of a constellation of otherwise non-specific features, based on an understanding of the underlying pathophysiology. Whereas echocardiographic examination is a central component of diagnosis, alone it is insufficient to establish the physiologic diagnosis of hemodynamically significant cardiac tamponade. The hemodynamic diagnosis of cardiac tamponade requires clinical evidence of low cardiac output and stroke volume in the setting of elevated cardiac filling pressures, with evidence of increased sympathetic tone (tachycardia, peripheral vasoconstriction, etc), and exclusion of other causes of shock as the primary problem (particularly cardiogenic shock)...

BACKGROUND: The aim of this study was to report outcomes and late toxicity following hypofractionated accelerated radiotherapy for T2 glottic cancers. We highlight the importance of hypofractionated treatments with shorter overall treatment times, in improving outcomes for T2 glottic cancers. We also compare the biologically effective dose of hypofractionated regimes, with conventional fractionation. METHODS: One hundred twelve patients with T2 glottic cancer were treated between January 1999 and December 2005...

Kidney transplant patients treated with belatacept without depletional induction experience higher rates of acute rejection compared to patients treated with conventional immunosuppression. Costimulation blockade-resistant rejection (CoBRR) is associated with terminally differentiated T cells. Alemtuzumab induction and belatacept/sirolimus immunotherapy effectively prevents CoBRR. We hypothesized that cells in late phases of differentiation would be selectively less capable of repopulating post-depletion than more naïve phenotypes, providing a potential mechanism by which lymphocyte depletion and repopulation could reduce the risk of CoBRR...

Potassium channels play an important role in modulating synaptic activity both at presynaptic and postsynaptic levels. We have shown before that presynaptically located KV and KIR channels modulate the strength of corticostriatal synapses in rat brain, but the role of other types of potassium channels at these synapses remains largely unknown. Here we show that calcium-dependent potassium channels BK-type but not SK-type channels are located presynaptically in corticostriatal synapses. We stimulated cortical neurons in rat brain slices and recorded postsynaptic excitatory potentials (EPSP) in medium spiny neurons (MSN) in dorsal neostriatum...

Human papilloma virus positive (HPV+) tumors represent a large proportion of anal, vulvar, vaginal, cervical and head and neck squamous carcinomas (HNSCC) and late stage invasive disease is thought to originate from a premalignant state. Cyclic dinucleotides that activate STimulator of INterferon Genes (STING) have been shown to cause rapid regression of a range of advanced tumors. We aimed to investigate STING ligands as a novel treatment for papilloma. We tested therapies in a spontaneous mouse model of papilloma of the face and anogenital region that histologically resembles human HPV-associated papilloma...

Coniine, a polyketide-derived alkaloid, is poisonous to humans and animals. It is a nicotinic acetylcholine receptor antagonist, which leads to inhibition of the nervous system, eventually causing death by suffocation in mammals. Coniine's most famous victim is Socrates who was sentenced to death by poison chalice containing poison hemlock in 399 BC. In chemistry, coniine holds two historical records: It is the first alkaloid the chemical structure of which was established (in 1881), and that was chemically synthesized (in 1886)...

OBJECTIVE: We aimed to evaluate the use of miR-200b as a prenatal transplacental therapy in the nitrofen rat model of abnormal lung development and congenital diaphragmatic hernia (CDH). BACKGROUND: Pulmonary hypoplasia (PH) and pulmonary hypertension determine mortality and morbidity in CDH babies. There is no safe medical prenatal treatment available. We previously discovered that higher miR-200b is associated with better survival in CDH babies. Here, we investigate the role of miR-200b in the nitrofen rat model of PH and CDH and evaluate its use as an in vivo prenatal therapy...
