1435259 Electroluminescence BOFORS AB 4 Sept 1974 [4 Sept 1973] 38741/74 Heading C4S [Also in Division H1] In order to protect a light-emitting diode from precipitation of condensed water vapour when the diode is cooled, e.g. by a liquid coolant 8, a sleeve 9 of good thermal conductivity is applied to the diode casing with good thermal contact, e.g. by force-fitting or chemical bonding. The sleeve 9 acts as a cold trap on which water preferentially condenses. In the embodiment the casing (4) (also Fig. 1, not shown) is of steel with a glass end window, the sleeve 9 is of copper and the diode is mounted in a cooled holder 6 having a glass outer window 7. The diode may be a laser or other L.E.D.
Dermal carcinogenicity testing has not been performed with tretinoin gel (microsphere), 0.1%, 0.08%, 0.06% or 0.04%.

In a 91-week dermal study in which CD-1 mice were administered 0.017% and 0.035% formulations of tretinoin, cutaneous squamous cell carcinomas and papillomas in the treatment area were observed in some female mice. These concentrations are near the tretinoin concentration of the 0.04% and 0.1% clinical formulations. A dose-related incidence of liver tumors in male mice was observed at those same doses. The maximum systemic doses associated with the administered 0.017% and 0.035% formulations are 0.5 and 1.0 mg/kg/day tretinoin, respectively. These doses are two and four times the MRHD based on BSA comparison.

The biological significance of these findings is not clear because they occurred at doses that exceeded the dermal maximally tolerated dose of tretinoin and because they were within the background natural occurrence rate for these tumors in this strain of mice.

There was no evidence of carcinogenic potential when 0.025 mg/kg/day of tretinoin was administered topically to mice (0.1 times the MRHD based on BSA comparison). Studies in hairless albino mice suggest that concurrent exposure to tretinoin may enhance the tumorigenic potential of carcinogenic doses of UVB and UVA light from a solar simulator. This effect has been confirmed in a later study in pigmented mice, and dark pigmentation did not overcome the enhancement of photocarcinogenesis by 0.05% tretinoin. Although the significance of these studies to humans is not clear, patients should minimize exposure to sunlight or artificial ultraviolet irradiation sources [see Warnings and Precautions (5.2)].

The genotoxic potential of tretinoin was evaluated in the Ames assay and in the in vivo mouse micronucleus assay, both of which were negative.

The components of the microspheres have shown potential for genetic toxicity and fetal malformation. EGDMA, a component of the excipient acrylates copolymer, was positive for induction of structural chromosomal aberrations in the in vitro chromosomal aberration assay in mammalian cells in the absence of metabolic activation, and negative for genetic toxicity in the Ames assay, and the in vivo mouse micronucleus assay.

In oral fertility studies in rats with tretinoin, the no-observable effect level was 2 mg/kg/day (19 times the MRHD based on BSA comparison).
Use in Specific Populations

Pregnancy— 

Advise women to notify their healthcare provider if they become pregnant or intend to become pregnant during treatment with olanzapine orally disintegrating tablets. Advise patients that olanzapine may cause extrapyramidal and/or withdrawal symptoms (agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress, and feeding disorder) in a neonate. Advise patients that there is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to olanzapine during pregnancy [see Use in Specific Populations ( 8.1)] . 

Lactation— Advise breastfeeding women using olanzapine orally disintegrating tablets to monitor infants for excess sedation, irritability, poor feeding and extrapyramidal symptoms (tremors and abnormal muscle movements) and to seek medical care if they notice these signs. [see Use in Specific Populations ( 8.2)] . 

Infertility— Advise females of reproductive potential that olanzapine orally disintegrating tablets may impair fertility due to an increase in serum prolactin levels. The effects on fertility are reversible [see Use in Specific Populations ( 8.3)] . 

Pediatric Use— Olanzapine orally disintegrating tablets are indicated for treatment of schizophrenia and manic or mixed episodes associated with bipolar I disorder in adolescents 13 to 17 years of age. Compared to patients from adult clinical trials, adolescents were likely to gain more weight, experience increased sedation, and have greater increases in total cholesterol, triglycerides, LDL cholesterol, prolactin, and hepatic aminotransferase levels. Patients should be counseled about the potential long-term risks associated with olanzapine orally disintegrating tablets and advised that these risks may lead them to consider other drugs first [see Indications and Usage ( 1.1, 1.2)] . Safety and effectiveness of olanzapine orally disintegrating tablets in patients under 13 years of age have not been established. Safety and efficacy of olanzapine orally disintegrating tablets and fluoxetine in combination in patients 10 to 17 years of age have been established for the acute treatment of depressive episodes associated with bipolar I disorder. Safety and effectiveness of olanzapine orally disintegrating tablets and fluoxetine in combination in patients <10 years of age have not been established [see Warnings and Precautions ( 5.5) and Use in Specific Populations ( 8.4)] .
The hypothalamus receives serotonergic projections from the raphe nucleus in a sex-specific manner. During systemic inflammation, hypothalamic levels of serotonin (5-hydroxytryptamine [5-HT]) decrease in male rats. The present study evaluated the involvement of endothelin-1 (ET-1) in the febrile response, hypolocomotion, and changes in hypothalamic 5-HT levels during systemic inflammation in male and female rats. An intraperitoneal injection of lipopolysaccharide (LPS) induced a febrile response and hypolocomotion in both male and female rats. However, although LPS reduced hypothalamic levels of 5-HT and its metabolite 5-hydroxyindol acetic acid (5-HIAA) in male rats, it increased these levels in female rats. An intracerebroventricular injection of the endothelin-B receptor antagonist BQ788 significantly reduced LPS-induced fever and hypolocomotion and changes in hypothalamic 5-HT and 5-HIAA levels in both male and female rats. The i.c.v. administration of ET-1 induced a significant fever and hypolocomotion, but reduced the hypothalamic levels of 5-HT and 5-HIAA in both males and females. These results suggest an important sexual dimorphism during systemic inflammation regarding the release of 5-HT in the hypothalamus. Moreover, ET-1 arises as an important mediator involved in the changes in hypothalamic 5-HT levels in both male and female rats.

This invention relates to agents that regulate the proliferation of cells such as smooth muscle cells. Proliferation of smooth muscle cells may be increased or decreased by affecting the activity or concentration of a transcription factor. The factor comprises two domains of about 50 kD and about 70 kD which together have an approximate molecular weight of 120 kD and specifically binds to the nucleic acid sequence 5'-GGGTTTTCCCC-3' (SEQ ID NO 2). This factor represents a novel member of the family of rel-related factors. This invention also relates to methods for the treatment and prevention of diseases and disorders associated with proliferation of smooth muscle cells such as arteriosclerosis, fibrosis and wound healing, which involve regulation of the smooth muscle cell transcription factor. The invention further relates to purified transcription factor, to pharmaceutical compositions containing transcription factor or inhibitors or inducers of the transcription factor, to nucleic acid sequences which code for the subunits of the factor, and to recombinant cells transformed with these sequences. Novel rel-related factors can also be used to regulate gene expression and the proliferation of organisms such as cells and viruses which may contain rel-related binding elements.
BACKGROUND & AIMS: Gastric cancer is often accompanied by a loss of mucin 6 (MUC6), but its pathogenic role in gastric carcinogenesis remains unclear.
METHODS: Muc6 knockout (Muc6-/-) mice and Muc6-dsRED mice were newly generated. Tff1Cre, Golph3-/-, R26-Golgi-mCherry, Hes1flox/flox, Cosmcflox/flox, and A4gnt-/- mice were also used. Histology, DNA and RNA, proteins, and sugar chains were analyzed by whole-exon DNA sequence, RNA sequence, immunohistochemistry, lectin-binding assays, and liquid chromatography-mass spectrometry analysis. Gastric organoids and cell lines were used for in vitro assays and xenograft experiments.
RESULTS: Deletion of Muc6 in mice spontaneously causes pan-gastritis and invasive gastric cancers. Muc6-deficient tumor growth was dependent on mitogen-activated protein kinase activation, mediated by Golgi stress-induced up-regulation of Golgi phosphoprotein 3. Glycomic profiling revealed aberrant expression of mannose-rich N-linked glycans in gastric tumors, detected with banana lectin in association with lack of MUC6 expression. We identified a precursor of clusterin as a binding partner of mannose glycans. Mitogen-activated protein kinase activation, Golgi stress responses, and aberrant mannose expression are found in separate Cosmc- and A4gnt-deficient mouse models that lack normal O-glycosylation. Banana lectin-drug conjugates proved an effective treatment for mannose-rich murine and human gastric cancer.
CONCLUSIONS: We propose that Golgi stress responses and aberrant glycans are important drivers of and promising new therapeutic targets for gastric cancer.
Traumatic brain injury (TBI) alters brain network connectivity. Structural covariance networks (SCNs) reflect morphological covariation between brain regions. SCNs may elucidate how altered brain network topology in TBI influences long-term outcomes. Here, we assessed whether SCN organisation is altered in individuals with chronic moderate-severe TBI (≥ 10 years post-injury) and associations with cognitive performance. This case-control study included fifty individuals with chronic moderate-severe TBI compared to 75 healthy controls recruited from an ongoing longitudinal head injury outcome study. SCNs were constructed using grey matter volume measurements from T1-weighted MRI images. Global and regional SCN organisation in relation to group membership and cognitive ability was examined using regression analyses. Globally, TBI participants had reduced small-worldness, longer characteristic path length, higher clustering, and higher modularity globally (p < 0.05). Regionally, TBI participants had greater betweenness centrality (p < 0.05) in frontal and central areas of the cortex. No significant associations were observed between global network measures and cognitive ability in participants with TBI (p > 0.05). Chronic moderate-severe TBI was associated with a shift towards a more segregated global network topology and altered organisation in frontal and central brain regions. There was no evidence that SCNs are associated with cognition.
BACKGROUND: Since the introduction of combination antiretroviral therapy (cART) the brain has become an important human immunodeficiency virus (HIV) reservoir due to the relatively low penetration of many drugs utilized in cART into the central nervous system (CNS). Given the inherent limitations of directly assessing acute HIV infection in the brains of people living with HIV (PLWH), animal models, such as humanized mouse models, offer the most effective means of studying the effects of different viral strains and their impact on HIV infection in the CNS. To evaluate CNS pathology during HIV-1 infection in the humanized bone marrow/liver/thymus (BLT) mouse model, a histological analysis was conducted on five CNS regions, including the frontal cortex, hippocampus, striatum, cerebellum, and spinal cord, to delineate the neuronal (MAP2ab, NeuN) and neuroinflammatory (GFAP, Iba-1) changes induced by two viral strains after 2 weeks and 8 weeks post-infection.
RESULTS: Findings reveal HIV-infected human cells in the brain of HIV-infected BLT mice, demonstrating HIV neuroinvasion. Further, both viral strains, HIV-1JR-CSF and HIV-1CH040, induced neuronal injury and astrogliosis across all CNS regions following HIV infection at both time points, as demonstrated by decreases in MAP2ab and increases in GFAP fluorescence signal, respectively. Importantly, infection with HIV-1JR-CSF had more prominent effects on neuronal health in specific CNS regions compared to HIV-1CH040 infection, with decreasing number of NeuN+ neurons, specifically in the frontal cortex. On the other hand, infection with HIV-1CH040 demonstrated more prominent effects on neuroinflammation, assessed by an increase in GFAP signal and/or an increase in number of Iba-1+ microglia, across CNS regions.
CONCLUSION: These findings demonstrate that CNS pathology is widespread during acute HIV infection. However, neuronal loss and the magnitude of neuroinflammation in the CNS is strain dependent indicating that strains of HIV cause differential CNS pathologies.
The oral squamous cell carcinoma (OSCC) 5 year survival rate of 41% has marginally improved in the last few years, with less than a 1% improvement per year from 2005 to 2017, with higher survival rates when detected at early stages. Based on histopathological grading of oral dysplasia, it is estimated that severe dysplasia has a malignant transformation rate of 7%-50%. Despite these numbers, oral dysplasia grading does not reliably predict its clinical behavior. Thus, more accurate markers predicting oral dysplasia progression to cancer would enable better targeting of these lesions for closer follow-up, especially in the early stages of the disease. In this context, molecular biomarkers derived from genetics, proteins, and metabolites play key roles in clinical oncology. These molecular signatures can help predict the likelihood of OSCC development and/or progression and have the potential to detect the disease at an early stage and, support treatment decision-making and predict treatment responsiveness. Also, identifying reliable biomarkers for OSCC detection that can be obtained non-invasively would enhance management of OSCC. This review will discuss biomarkers for OSCC that have emerged from different biological areas, including genomics, transcriptomics, proteomics, metabolomics, immunomics, and microbiomics.
The primary outcome was incidence of PONV that occurred within 3 days after the operation. The investigators defined PONV as a presence of either nausea or vomiting. In study hospital, it was routine for nurses to assess and record nausea and vomiting every 8 hours for all postoperative patients during postoperative 3 days. Accordingly, the investigators retrospectively collected the presence of PONV from electrical medical records. If patients had discharged hospital within postoperative 3 days, the incidence of PONV was assessed solely during hospital stay. The data, collected included information regarding age at surgery, gender, and type of strabismus. During strabismus surgery, the number and sequence of the operated muscles, HR before traction of the EOM (baseline HR), maximum decreased HR after traction of the EOM, HR at maximum recovery from decreased HR and maintained during traction of the EOM (adrenergic HR), and HR at the cutting of the muscle, were collected. Oculocardiac reflex was defined as a decrease in HR greater than or equal to 20% rather than maximum at first traction of the muscle.
As one of the most common malignancies, colorectal cancer (CRC) usually starts with a benign lesion and accumulates DNA damage as it progresses to full-fledged cancer. Glycyrrhizin (GL) has been found to alleviate tumor growth and inflammation, while the role of GL influences DNA damage response (DDR) in colorectal cancer remains unclear. GL exposure significantly reduced cell colony formation and viability with a concomitant increase in DNA fragmentation in CRC, meanwhile GL induced apoptosis by activating caspase-3. Moreover, GL induced cell cycle arrest in CRC cells at S phase, which was associated with decreased cyclin D1 in vitro. GL treatment significantly ameliorated tumor growth and promoted DDR in vivo. Mechanism analysis revealed that GL significantly downregulated the NHEJ pathway via inhibiting HMGB1. Finally, the expression of HMGB1 was abnormal regulated in CRC tissue than in adjacent normal tissues and associated with TNM stage and overall survival. Our findings indicate that HMGB1 may be a novel therapeutic target in CRC, a result that GL may serve as a promising drug for CRC treatment.
Elevations in state anxiety, when moderate and temporary, serve an adaptive function in pandemic contexts, facilitating health behaviors like self-protection and social distancing. However, for some people elevated state anxiety transitions to anxiety disorders, creating undue suffering and impairment. Nearly 33% of both Wuhan residents and Chinese citizens screened positive for generalized anxiety disorder during the COVID-19 pandemic, with uncontrollable, persistent COVID-19-related worries strongly predicting presence of GAD. Similarly, large surveys indicate that levels of anxiety symptoms are rising among United States citizens.

This finding aligns with a large body of literature indicating stronger perceived control over one's own anxiety buffers against a variety of anxiety disorders. Thus, in the context of COVID-19, there is a pressing need for materials that might strengthen perceived control over anxiety, thereby reducing risk for anxiety disorder onset. Ideally, such materials would (1) in no way undermine positive health behaviors, like social distancing, and (2) have capacity for broad-scale, immediate accessibility. Internet-based interventions may particularly valuable during the pandemic stage of COVID-19 due to the need for social distancing, and they have already scaled up to address needs in China. However, drop out from internet-based interventions can be up to 83% and intervention engagement is a frequent issue. Fortunately, single-session experiences (SSEs) can improve mental health related outcomes with similar effect sizes as multi-session therapies, and pilot data from our team suggests they can increase general perceived control (within-group dz = 0.70).

The goal of this project is to test a web-based platform where people can confidentially access and provide feedback on brief activities, called 'single-session experiences' (SSEs), which are about 8 minutes in length, entirely self-administered, and computer-based (Contain COVID Anxiety and Project Remain COVID Free). Previous activities following the same best practices as these experiences have been shown to be safe to complete; predicted significant reductions in psychological distress; and are entirely self-administered. We will recruit a weighted-probability sample of the United States through Prolific's online platform, N = 500. All data collected from the SSEs will be confidential, and the only identifiable information that will be recorded is the participants' Prolific ID to facilitate compensation, which will be deleted from the data after the compensation has been paid. Those that choose to complete the activities have the option to submit their advice to their peers and have it posted anonymously to the web-based platform. This will provide people with an option for an easily accessible activity designed to promote healthy coping skills and resilience in a welcoming environment through which they can learn with others and share experiences.
Biodegradable shape memory polymer compositions, articles of manufacture thereof, and methods of preparation and use thereof are described. In one embodiment the compositions include at least one hard segment and at least one soft segment. The Ttrans of the hard segment is preferably between -30 and 270 °C. At least one of the hard or soft segments can contain a cross-linkable group, and the segments can be linked by formation of an interpenetrating network or a semi-interpenetrating network, or by physical interactions of the segments. Objects can be formed into a given shape at a temperature above the Ttrans of the hard segment, and cooled to a temperature below the Ttrans of the soft segment. If the object is subsequently formed into a second shape, the object can return to its original shape by heating the object above the Ttrans of the soft segment and below the Ttrans of the hard segment.
Heart failure (HF) is a complex syndrome which results from structural and/or functional alterations that limit the ability to respond to physiological demands(1,2).These abnormalities involve metabolic and neuro-hormonal factors such as tumor necrosis factor-α (TNF-α), one of the most important catabolic cytokines related with changes in body composition, interleukin 1 (IL-1), IL-6, interferon Y, and transmission growth factor β (3-9), which produce catabolic and anabolic imbalance and promote loss of fat free mass (FFM) with or without loss of fat mass (FM) in patients with HF. This syndrome is called "Cardiac Cachexia" (CC) (10). Signs and symptoms such as fatigue, anorexia and decreased muscle strength reflect altered body composition (9, 10). There are two possible ways to counteract these catabolic factors and restore body compartments. In one of them, protein supplementation promotes protein synthesis and inhibits proteolysis (3,11,12); in the other resistance exercise (RE) increases muscle mass and muscle strength, maintaining heart rate (13,14). Previous studies report the association of protein supplementation (15-17) and exercise (18-23) with changes in muscle strength in some cases and exercise capacity in HF patients. However, these therapies were not combined, and the studies did not provide enough information about changes in body composition. Based on these reports, our hypothesis is that the combination of RE and protein supplementation in form of branched chain amino acids (BCAA) might have an anabolic effect in patients with HF since the supplementation of BCAA could be helpful as "fuel" during the exercise and maintain the muscle mass metabolism (24).
Forty five (45) participants will be recruited and randomized into 3 arms (1:1:1). Fifteen (15) patients in arm 1 (group 1) will receive the matching placebo powder orally once daily for 12 weeks (90 days).
