The mechanical heart valve prosthesis with a caged ball has been around for 60 years. It has since experienced changes and adjustments. The Starr–Edwards (SE) valve was a pioneer and was taken out of clinical use in the late 2000s. SE is reportedly close to or has reached the age of 50, according to numerous sources from around the globe. The author’s observations and review of the literature about thrombogenicity, pannus formation, left ventricular outflow tract obstructions, and infective endocarditis in the SE valves, which were reportedly higher before its clinical ending, were only an overestimation and were not supported by scientific data. However, it was less discussed in the article, along with potential benefits. The main reasons for its demise were its obtrusive size and unattractive shape. There have been several successful implantations of these valves in Asian nations and reports of fewer primary failures and unexpected cardiac fatalities. Therefore, there is a need for extensive data gathering, documentation, and more recent studies on these valves to prepare for a prospective revival of use with newer research, mainly when long-term durability is considered.

The subjective experience of consciousness, a cornerstone of human existence, is profoundly disrupted in disorders of consciousness (DOC) arising from severe brain injuries, spanning-states from coma to the minimally conscious state. A significant challenge in clinical practice is the phenomenon of covert consciousness, in which individuals may retain awareness despite the absence of overt behavioral responsiveness. Diagnosis based solely on observable behavior is inherently limited by factors such as co-occurring motor impairments, the fluctuating nature of consciousness, and subjective interpretation, potentially leading to misclassification. To overcome these limitations, neuroscientific methodologies have advanced significantly. To address these limitations, neuroscientific methods have advanced considerably. Functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) provide objective evidence of preserved brain activity and cognitive processing, enabling detection of willful modulation and offering prognostic insight. Electrophysiological techniques—including electroencephalography (EEG), event-related potentials (ERPs), transcranial magnetic stimulation combined with EEG (TMS-EEG), and advanced downstate analysis—further reveal dynamic neural patterns indicative of residual awareness. The detection of covert consciousness has profound ethical, clinical, and societal implications. It necessitates a re-examination of patient rights, end-of-life decision-making, the use of brain-computer interfaces, and societal conceptions of personhood. This evolving understanding mandates a shift towards integrating objective neuroscientific assessments with compassionate, person-centered care, aiming to preserve dignity and navigate the complex ethical landscape of severe brain injury.
A major hallmark of Parkinson's disease is loss of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The pathophysiological mechanisms causing this relatively selective neurodegeneration are poorly understood, and thus experimental systems allowing to study dopaminergic neuron dysfunction are needed. Induced pluripotent stem cells (iPSCs) differentiated toward a dopaminergic neuronal phenotype offer a valuable source to generate human dopaminergic neurons. However, currently available protocols result in a highly variable yield of dopaminergic neurons depending on the source of hiPSCs. We have now developed a protocol based on HBA promoter-driven transient expression of transcription factors by means of adeno-associated viral (AAV) vectors, that allowed to generate very consistent numbers of dopaminergic neurons from four different human iPSC lines. We also demonstrate that AAV vectors expressing reporter genes from a neuron-specific hSyn1 promoter can serve as surrogate markers for maturation of hiPSC-derived dopaminergic neurons. Dopaminergic neurons differentiated by transcription factor expression showed aggravated neurodegeneration through α-synuclein overexpression, but were not sensitive to γ-synuclein overexpression, suggesting that these neurons are well suited to study neurodegeneration in the context of Parkinson’s disease.

Background: Malaria is a systemic disease caused by various species of Plasmodium, transmitted through the bite of a female Anopheles mosquito. According to the World Health Organisation, there were 214 million cases of malaria worldwide in 2015. Nigeria’s burden of malaria is about 51million cases and 207,000 deaths annually, accounting for 60% of outpatient visits to hospitals, 11% of maternal mortality, and 30% of child mortality. The study aimed to compare RDT and microscopy in malaria diagnosis in a District Hospital in Enugu state, Southeast Nigeria. Methods: Blood samples of 300 suspected cases of acute malaria were tested for malaria parasite using RDT and microscopy simultaneously. Results: In 2017, the study found a malaria prevalence of 25% (46.2% in children, and 18.1% in adults) in Awgu. RDT was positive in 38% and microscopy in 70.3% of cases. Both RDT and microscopy were positive in 36.3%, negative in 28.3%, and discordant in 35.4%. Sensitivity of RDT was 50.7% (89.4% in children, and 25.6% in adults). RDT had a specificity of 100% (both children and adults), positive predictive value of 1 (both children and adults), and negative predictive value of 0.6 (0.5 in children, 0.6 in adults). Conclusions: RDT (SD Malaria Ag P. f) had more sensitivity in children (89.4%) than adults (25.6%), and the occurrence of false negative results was more in adults (46.8%) than children (9.5%). All negative RDT results need to be examined microscopically, to rule out false negative cases.

In some countries, a high percentage of the population relies on traditional plants for treating certain diseases. The aim of this study was to investigate the effect of G. alypum extract (GAE) and Alhagj marorum extract (AME) on lipid profiles in experimentally induced hypercholesteremic rats and on the blood pressure of experimentally induced hypertensive rats. Male Wistar rats weighing 200 - 300 g were divided into five groups: group 1 received a normal diet (negative control), group 2 received a high lipid diet containing coconut oil (10 g/kg/day), cholesterol (4 g/kg/day) and cholic acid (0.20 g/kg/day) (positive control), group 3 received a high lipid diet together with clofibrate (50 mg/kg/day), group 4 received a high lipid diet together with AME (200 mg/kg/day) and group 5 received GAE (200 mg/kg/day). The experiment continued for two weeks, then the rats were sacrificed and blood samples were collected for estimation of cholesterol, triglycerides, high-density lipoprotein and low-density lipoprotein. To induce hypertension, rats were divided into two groups (n = 8 in each group). Group 1 received normal saline (control) and Group 2 received dexamethasone (0.40 mg/kg, i.p.) for seven consecutive days. Later, the rats were anesthetized using thiopental and the carotid artery was cannulated for recording blood pressure. AME (40 mg/kg) or GAE (40 mg/kg) were injected through a cannula placed into the internal jugular vein at a dose volume of 0.1 ml. Systolic and diastolic blood pressure were measured before and after plant extract administration. The results showed that clofibrate GAE extract and ANE extract significantly decreased cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein as compared to high-lipid diet-treated rats. Data also indicated that administration of GAE or AME extract significantly decreased systolic and diastolic blood pressure in experimentally induced hypertensive rats. In conclusion, GAE and AME have antihyperlipidemic and antihypertensive activities and further investigation is needed to clarify the mechanism of these effects.

Vitamin C is associated with history of the cause of the ancient hemorrhagic disease scurvy. Vitamin C is an essential nutrient with important antioxidant properties. It is required by the body for normal physiological function. The body cannot synthesize vitamin C, it is present in nature through foods and other natural sources and it exists as a nutritional food supplement. The antioxidant activity of vitamin C protects the body from free radical damage. Vitamin C is essential for the development and maintenance of connective tissues. It is used as therapeutic agent in many diseases and disorders. Vitamin C plays an important role in several metabolic functions, as the conversion of the amino acid, tryptophan, to the neurotransmitter, serotonin, and the conversion of cholesterol to bile acids. Vitamin C supplementation resulted in a significant increase in vitamin C levels in populations; its high intake is associated with positive effects on cardiovascular risk factors. Vitamin C protects the immune system, reduces the severity of allergic reactions and helps to fight infections. It has an important role in bone formation, wound healing and the maintenance of healthy gums. There is profound beneficial effect of vitamin C in respect to human diseases as cancer, atherosclerosis, diabetes, neurodegenerative disease and many metal toxicities. Several vitamin C analogs have been produced as anticancer and antioxidant activity. Vitamin C is useful if it is used as adjuvant therapy for several chronic diseases. Thus, this review summarizes the importance of vitamin C in the body’s physiology and biochemistry, in addition, the different mechanisms that vitamin C is implicated to treat different acute and chronic diseases. Future exploration should pay attention to chronic disease management by vitamin C.

Cervical and ovarian cancers contribute significantly to female morbidity and mortality worldwide. The current standard of treatment, including surgical removal, radiation therapy, and chemotherapy, offers poor outcomes. There are many side effects to traditional chemotherapeutic agents and treatment-resistant types, and often, the immune response is depressed. As a result, conventional approaches have evolved to include new alternative remedies, such as natural compounds. Aquatic species provide a rich supply of possible drugs. The potential anti-cancer peptides are less toxic to normal cells and can attenuate multiple drug resistance by providing a productive treatment approach. The physiological effects of marine peptides are described in this review, which focuses on various pathways, such as apoptosis, microtubule balance disturbances, suppression of angiogenesis, cell migration/invasion, and cell viability. The review also highlights the potential role of marine peptides as safe and efficacious therapeutic agents for treating cervical and ovarian cancers.
The development of smart phone technology has lead to denigrate of the phone prepared with many sophisticated features such as sensors. Camera is one of the most extensively used sensors. Although the photographs capture by camera can be shared via Multimedia Message Service (MMS) which allows broadcast of files like photographs, audio and video. A major problem of MMS is, it doesn’t provide adequate safety mechanism. Because of this, the data of the people who wants to conceal confidential information from state-controlled systems that can be easily monitored. Video Steganography is a technique to hide any type of files in any extension into a Video file. The idea proposed in this paper is to embed any kind of data in another file, which is called carrier file. The carrier file must be image video file. Steganography is the art of hiding messages inside other messages such that the very existence of the message is unknown to third party. In this paper, a steganography-based android mobile application that can insert the confidential information into an image, then into a video that can be send it to receiver. Finally we can extract the confidential information from the image in the receiver side.

In the present study the effect of the ethanol extract of Culcasia falcifolia on the neurotransmitter levels were evaluated. Pentylenetetrazole (PTZ) (60 mg/kg body weight, i. p) was administered to all the groups of mice to induce convulsions. After observing the convulsion, all groups rats were sacrificed, whole brain was dissected out and separated the forebrain. The brain tissue was homogenized and then centrifuged. The aqueous phase was taken for the assay. The reading was obtained using spectroflurimeter. The result of the present study shows that the ethanol extract of Culcasia falcifolia at the dose of 200 and 400 mg/kg body weight significantly increased the level of inhibitory neurotransmitter GABA and also showed significant increase in the levels of dopamine, noradrenalin and serotonin when compared to seizure control group (PTZ treated group) and was almost equivalent to control group. The findings of the study showed that the extract at 200 and 400 mg/kg body weight significantly (p<0.001) increased the levels of GABA, dopamine, serotonin and noradrenaline. The ethanol extract of Culcasia falcifolia exerted antiepileptic activity by decreasing seizure susceptibility to pentylenetetrazole-induced seizure in mice due to restoration of GABA, serotonin, dopamine and noradrenaline concentration levels in mice brain.
