Angioid Streaks and Choroidal Neovascular Membrane Secondary to Pseudoxanthoma Elasticum: A Case Report.

Angioid streaks (AS) are recognized as irregular, linear dehiscences of Bruch's membrane, often associated with systemic diseases. We present the case of a 50-year-old woman initially diagnosed with AS during a routine optometric examination. Subsequent ophthalmological evaluation revealed bilateral AS with calcified drusen. Two years post-diagnosis, she developed blurred vision in her right eye due to the choroidal neovascular membrane adjacent to the macular AS. Further evaluation uncovered clinical signs consistent with pseudoxanthoma elasticum (PXE), including characteristic skin lesions. A multidisciplinary approach involving ophthalmology, dermatology, and cardiovascular specialists was initiated. Histopathological confirmation of PXE was obtained through a skin biopsy. PXE, an autosomal recessive disorder characterized by elastin calcification, presents systemic manifestations necessitating comprehensive evaluation and monitoring. This case demonstrates the importance of recognizing ocular complications in PXE and advocates for early multidisciplinary intervention to mitigate potential vision and life-threatening outcomes.

Protective Assessment of Novel (Bncs Formulation) against Brain Tumor.

BACKGROUND: Oxidative stress refers to non-homeostatic elevation within intracellular reactive oxygen species (ROS) levels and is associated with several neuro-related pathological conditions. Diclofenac is a commonly prescribed non-steroidal anti-inflammatory drug (NSAID) for treating aches and pain by reducing inflammation. Diclofenac is also associated with the induction of apoptotic cell death by altering the homeostatic balance within mitochondria. In the present report, the neuroprotective effects of BNC formulation constituted by Bacopa monnieri leaves, Nigella sativa and Curcuma longa rhizome seeds were investigated. METHODS: The synthesized formulation was characterized using FT-IR and LC-MS along with organoleptic evaluation. Thereafter neuroprotective efficacy of BNC formulation was subsequently investigated against Diclofenac-induced oxidative stress in SH-SY5Y cells. The cells were pretreated with synthesized formulation and subsequently evaluated for amelioration in Diclofenac-induced cytotoxicity, and ROS augmentation. The neuroprotective effect of synthesized formulation was further explored by evaluating the changes in nuclear morphology, and apoptosis alleviation with concomitant regulatory effects on caspase-3 and -9 activation. RESULTS: Diclofenac was found to be considerably cytotoxic against human neuroblastoma SHSY5Y cells. Intriguingly, Diclofenac-mediated toxicity was reduced significantly in SH-SY5Y cells pretreated with BNC formulation. Augmented ROS levels within Diclofenac-treated SHSY5Y cells were also reduced in the BNC formulation pretreated SH-SY5Y cells. Furthermore, BNC formulation pretreated SH-SY5Y cells also exhibited reduced dissipation of mitochondrial membrane potential, caspase-3 and -9, along with apoptosis after Diclofenac treatment. CONCLUSION: These findings indicated that, indeed, Diclofenac induces considerable ROSmediated apoptosis in SH-SY5Y cells, which further intriguingly ameliorated Diclofenacmediated cytotoxic effects on SH-SY5Y cells. This manuscript further collected information about available National and International patents published or granted in preparation of and thereof applications against motor and non-motor brain dysfunctions.

Development of a standardized Canadian undergraduate medical education ophthalmology curriculum.

OBJECTIVE: To create a standardized undergraduate medicine ophthalmology curriculum for Canadian medical schools. DESIGN: Two-stage modified Delphi technique. PARTICIPANTS: Undergraduate ophthalmology leads at all the medical schools in Canada and 6 nonophthalmologist physicians with medical education expertise. METHODS: In stage 1, a preliminary list of curricular objectives was developed using the 2018 Association of University Professors in Ophthalmology's list of curricular objectives as a foundation. Subsequently, an online survey was sent to 24 individuals (18 ophthalmology undergraduate curriculum leads and 6 non-ophthalmology medical educators) at 17 institutions to evaluate the objectives using a 5-point Likert-type scale. In stage 2, the ophthalmology curriculum leads were invited to participate in a virtual meeting during which the list of curricular objectives was discussed and finalized by consensus. RESULTS: In stage 1, a preliminary list of 76 learning objectives organized into 10 overarching topics was developed. A total of 21 survey responses were received (87.5% response rate), allowing for the creation of a revised list. In stage 2, five participants from four schools met, achieving consensus following one round of feedback. The final undergraduate ophthalmology curriculum contained 10 topics and 75 objectives; it covered common presentations of a variety of acute and chronic eye diseases that were felt to be relevant to a wide medical audience. CONCLUSIONS: The consensus obtained on a comprehensive list of undergraduate medicine ophthalmology curricular objectives identified in this study is the first of its kind in Canada. These objectives can be used by medical schools across Canada to standardize undergraduate ophthalmology teaching.

Bisphenol A contamination in aquatic environments: a review of sources, environmental concerns, and microbial remediation.

The production of polycarbonate, a high-performance transparent plastic, employs bisphenol A, which is a prominent endocrine-disrupting compound. Polycarbonates are frequently used in the manufacturing of food, bottles, storage containers for newborns, and beverage packaging materials. Global production of BPA in 2022 was estimated to be in the region of 10 million tonnes. About 65-70% of all bisphenol A is used to make polycarbonate plastics. Bisphenol A leaches from improperly disposed plastic items and enters the environment through wastewater from plastic-producing industries, contaminating, sediments, surface water, and ground water. The concentration BPA in industrial and domestic wastewater ranges from 16 to 1465 ng/L while in surface water it has been detected 170-3113 ng/L. Wastewater treatment can be highly effective at removing BPA, giving reductions of 91-98%. Regardless, the remaining 2-9% of BPA will continue through to the environment, with low levels of BPA commonly observed in surface water and sediment in the USA and Europe. The health effects of BPA have been the subject of prolonged public and scientific debate, with PubMed listing more than 17,000 scientific papers as of 2023. Bisphenol A poses environmental and health hazards in aquatic systems, affecting ecosystems and human health. While several studies have revealed its presence in aqueous streams, environmentally sound technologies should be explored for its removal from the contaminated environment. Concern is mostly related to its estrogen-like activity, although it can interact with other receptor systems as an endocrine-disrupting chemical. Present review article encompasses the updated information on sources, environmental concerns, and sustainable remediation techniques for bisphenol A removal from aquatic ecosystems, discussing gaps, constraints, and future research requirements.

Protein Kinases and their Inhibitors Implications in Modulating Disease Progression.

Protein phosphorylation plays an important role in cellular pathways, including cell cycle regulation, metabolism, differentiation and survival. The protein kinase superfamily network consists of 518 members involved in intrinsic or extrinsic interaction processes. Protein kinases are divided into two categories based on their ability to phosphorylate tyrosine, serine, and threonine residues. The complexity of the system implies its vulnerability. Any changes in the pathways of protein kinases may be implicated in pathological processes. Therefore, they are regarded as having an important role in human diseases and represent prospective therapeutic targets. This article provides a review of the protein kinase inhibitors approved by the FDA. Finally, we summarize the mechanism of action of protein kinases, including their role in the development and progression of protein kinase-related roles in various pathological conditions and the future therapeutic potential of protein kinase inhibitors, along with links to protein kinase databases. Further clinical studies aimed at examining the sequence of protein kinase inhibitor availability would better utilize current protein kinase inhibitors in diseases. Additionally, this review may help researchers and biochemists find new potent and selective protein kinase inhibitors and provide more indications for using existing drugs.

Phytopharmaceuticals and Herbal Approaches to Target Neurodegenerative Disorders.

Neurodegeneration is characterized as the continuous functional and structural loss of neurons, resulting in various clinical and pathological manifestations and loss of functional anatomy. Medicinal plants have been oppressed from ancient years and are highly considered throughout the world as a rich source of therapeutic means for the prevention, treatment of various ailments. Plant-derived medicinal products are becoming popular in India and other nations. Further herbal therapies shows good impact on chronic long term illnesses including degenerative conditions of neurons and brain. The use of herbal medicines continues to expand rapidly across the world. The active phytochemical constituents of individual plants are sometimes insufficient to achieve the desirable therapeutic effects. Combining the multiple herbs in a particular ratio (polyherbalism) will give a better therapeutic effect and reduce toxicity. Herbal-based nanosystems are also being studied as a way to enhance the delivery and bioavailability of phytochemical compounds for the treatment of neurodegenerative diseases. This review mainly focuses on the importance of the herbal medicines, polyherbalism and herbal-based nanosystems and its clinical significance for neurodegenerative diseases.

Mitigation of cashew apple fruits astringency.

The cashew apple is a tropical pseudo fruit, with high fiber content, high nutritional value, and therapeutic compositional profile. Consuming cashew apples can help with several health-related problems, such as obesity, stomach ulcers, and gastritis. It has even demonstrated anti-tumor and anti-carcinogenic effects, and its antioxidants can help with wound-healing. Despite such benefits, the cashew apple is frequently considered as waste generated by cashew nut industries, since its commercial applications are restricted by the astringency and poor storability. This astringency is primarily due to the presence of tannins; and a lack of proper, efficient, and economical astringency reduction strategy is accountable for major waste generation. This review compiles pieces of information on the causes of astringency, as well as tannin reduction methods, such as clarification, thermal treatments, microfiltration, and fermentation. These methods aim to either just reduce tannin content or to valorize this by-product in a less-astringent better product. Both routes will eventually help with the better utilization of said organic food waste, which is critical for sustainable development.

Phytochemical Estimation and Therapeutic Amelioration of Aesculus hippocastanum L. Seeds Ethanolic Extract in Gastric Ulcer in Rats Possibly by Inhibiting Prostaglandin Synthesis.

OBJECTIVE: To quantify phytochemicals using liquid chromatography and mass spectroscopy (LCMS) analysis and explore the therapeutic effect of Aesculus hippocastanum L. (AH) seeds ethanolic extract against gastric ulcers in rats. METHODS: Preliminary phytochemical testing and LCMS analysis were performed according to standard methods. For treatment, the animals were divided into 7 groups including normal control, ulcer control, self-healing, AH seeds low and high doses, ranitidine and per se groups. Rats were orally administered with 10 mg/kg of indomethacin, excluding the normal control group (which received 1% carboxy methyl cellulose) and the per se group (received 200 mg/kg AH seeds extract). The test group rats were then given 2 doses of AH seeds extract (100 and 200 mg/kg, respectively), while the standard group was given ranitidine (50 mg/kg). On the 11th day, rats in all groups were sacrificed, and their stomach was isolated to calculate the ulcer index, and other parameters such as blood prostaglandin (PGE2), tissue superoxide dismutase (SOD), catalase (CAT), malonyldialdehyde (MDA), and glutathione (GSH). All isolated stomach tissues were analyzed for histopathological findings. RESULTS: The phytochemical examination shows that the AH seeds contain alkaloids, flavonoids, saponins, phenolic components, and glycosides. LCMS analysis confirms the presence of quercetin and rutin. The AH seeds extract showed significant improvement in gastric mucosa conditions after indomethacin-induced gastric lesions (P<0.01). Further marked improvement in blood PGE2 and antioxidant enzymes, SOD, CAT, MDA and GSH, were observed compared with self-healing and untreated ulcer-induced groups (P<0.01). Histopathology results confirmed that AH seeds extract improved the mucosal layer and gastric epithelial membrane in treated groups compared to untreated ulcer-induced groups. CONCLUSIONS: LCMS report confirms the presence of quercetin and rutin in AH seeds ethanolic extract. The therapeutic effect of AH seeds extract against indomethacin-induced ulcer in rat model indicated the regenerated membrane integrity, with improved cellular functions and mucus thickness. Further, improved antioxidant enzyme level would help to reduce PGE2 biosynthesis.

Influence of Plant Growth Regulators on Glandular Trichome Density and Steviol Glycosides Accumulation in Stevia rebaudiana.

With the advent of modern lifestyles, diabetes-related comorbidities attributed the importance of low-caloric natural sweetener plants such as Stevia rebaudiana. This plant is the viable source of steviol glycosides (SGs) and other economically important secondary metabolites. Glandular trichomes (GTs) play the role as a reservoir for all secondary products present in the plant species. Therefore, the present study was carried out to evaluate the influence of different plant growth regulators (PGRs) on GT density and its impact on the SG content. The direct shoot regeneration system was developed on Murashige and Skoog (MS) + benzyl aminopurine (BAP) (1.0 mg/L) + naphthaleneacetic acid (NAA) (0.5 mg/L), and MS + BAP (1.5 mg/L) + NAA (0.5 mg/L) from nodal and leaf explants, respectively. Among the combination of PGRs used, MS medium fortified with BAP (1.0 mg/L) and 2,4-dichlorophenoxyacetic acid (2,4-D) (0.5 mg/L) played a significant role in increasing the GT density on leaf and stem tissues of S. rebaudiana. Furthermore, high-performance thin-layer chromatography and gas chromatography-mass spectrophotometry data confirmed a notable rise in SGs and other valuable secondary metabolites. Thus, the protocol developed can be used for the propagation of stevia with an improved metabolic profile at a large scale.

Ethanolic extract of Coleus aromaticus leaves impedes the proliferation and instigates apoptotic cell death in liver cancer HepG2 cells through repressing JAK/STAT cascade.

Liver cancer or hepatocellular carcinoma (HCC) has become a leading cause for cancer burden across the globe, and incidences have tripled since the last two decades. Poor diagnosis of primary liver cancer and limited treatment strategies aggravate the challenges. Researchers globally have shown a steep inclination toward the exploration of plant-based compounds for their nutraceutical and anticancer potential to fit into the role of novel chemotherapeutics. Coleus aromaticus is a well-known culinary herb that earlier has been reported for several medicinal attributes. The current investigation deals with exploring the anticancer potential of ethanolic leaf extract of C. aromaticus (CoL-EtOH) against hepatocellular carcinoma HepG2 cell line. The observations made it evident that CoL-EtOH extract impeded the viability of HepG2 at 400 µg/ml (p < .01). Additionally, the extract also succeeded in escalating ROS production (p < .01) which aided dissipation of mitochondrial membrane potential and disruption of nuclear morphology. CoL-EtOH further activated caspase-8, -9, and -3 which was reaffirmed by increase in apoptosis at 400 µg/ml (p < .01). Moreover, post treatment with CaLEt-OH extract significantly reduced the expression of JAK-1 & STAT-3 genes (p < .01) along with regulated expression of Mcl1, Bcl-2, cyclinD1, p21, and p27 within HepG2 cells. This evidence portrays the promising anticancer potential of CoL-EtOH projecting it as a novel chemotherapeutic agent against HCC. PRACTICAL APPLICATIONS: The herb Coleus aromaticus belonging to Lamiaceae family and Coleus genus is known by various names in different regions of the world and several language-specific vernacular names. The herb has been used in therapeutic and medicinal applications as well as in culinary preparations. Various attributes of the nutritional strength and functional characteristics of the leaves in terms of carotenoids, minerals, phenols, dietary fiber, and antioxidant activity have been reported by several researchers. Carvacrol and thymol are majorly found in the plant, while chlorogenic acid and rosmarinic acid etc. as the phenolic components. The herb has been used in therapeutic and medicinal implications as well as in culinary preparations.

Hybrid nanocarriers for neurological disorders: Diagnostic & therapeutic Approach.

BACKGROUND: Around 1.5 billion people in the world were affected by complex neurological disorders and the figure is increasing alarmingly due to unsatisfactory clinical outcomes. To date, no conventional formulation is able to show a promising effect on the control or prevention of neurodegeneration. However, Nano delivery tools have shown better penetration and profound action on the targeted area of the brain. METHODS: Although existing Nano therapeutic approaches are abundant but would not reach the clinic due to their improper bioavailability, BBB restricts its entry and causes improper biodistribution, so it's a challenge to use certain bioactive as a potential therapy in neurodegenerative disorders. Hybrid nanocarriers are nano-vesicular transported systems, which could be utilized as carriers for the delivery of both hydrophilic and hydrophobic compounds. Available patents on nanodelivery for therapeutic approach will also include in this review. RESULTS: Hybrid Nano delivery system may provide good stability to polar and nonpolar compounds and improve their stability. CONCLUSION: This manuscript updates the available findings on the Nano vesicular system to deliver drugs for neurodegenerative disorders.

Loss of HOXA10 causes endometrial hyperplasia progressing to endometrial cancer.

Endometrial cancer is the fourth most common malignancy in women and the precursor lesion is endometrial hyperplasia. HOXA10 is a transcription factor that plays key roles in endometrial functions such as the endowment of receptivity, embryo implantation, and trophoblast invasion. Herein, using testicular transgenesis, we developed transgenic mice that expressed a shRNA against HOXA10 and there was a nearly 70% reduction in the expression of HOXA10 in these animals. We observed that downregulation of HOXA10 led to the development of endometrial hyperplasia in the young animals (3 months), and as they aged (>1 year), most animals developed well-differentiated endometrial adenocarcinoma. In the endometrium of animals with reduced HOXA10, there was increased proliferation and elevated levels of ERα and ERß. In parallel, there was increased expression of Wnt4 and ß-Catenin, SOX9, and YAP1. We propose that chronic reduction in HOXA10 expression disrupts multiple pathways in the uterus that aids in the development of endometrial hyperplasia which progresses to endometrial cancer with age.

Solid Lipid Nanoparticles of Lepidium Sativum L Seed Extract: Formulation, Optimization and In vitro Cytotoxicity Studies.

The current study focused on important bioactive compounds in plants that make them pharmacologically valuable. Therefore, this study was aimed to develop Lepidium sativum (L. sativum) seed extract loaded solid lipid nanoparticles and explore its cytotoxic effect on human liver cancer cells (HepG2 cells). The ethanolic extract of L. sativam used to develop L. sativum seed extract loaded solid lipid nanoparticles (SLNs) was analyzed by gas chromatography-mass spectrometry, thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC) for phytochemical profiling. The L. sativum seed extract loaded SLNs were efficaciously prepared by the nanoprecipitation method and screened on the basis of physicochemical properties. The L. sativum seed extract loaded SLN-2 was characterized using various parameters like particle size (237.1±0.104), % entrapment efficiency (80±1.15), zeta potential (42.1±0.102) and % drug release (45% at the end 8 hours and release the entire amount in 12 h). The SLN-2 formulation was optimized based on the recipient factor, and SLN-2 was used to further evaluate the in vitro cytotoxicity of HepG2 cells in a dose-dependent manner by 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay. The IC50 value of SLN2 was 52.37 ug/ml and sub IC50 26.1 ug/ml at 24 h and 48 h, respectively. Thus, we concluded that L. sativum extract loaded SLN-2 could act as an alternative therapy, possibly controlling therapeutic action by making a substantial reduction in side effects.
