RESUMO

There is almost no scientific literature available on the phytochemistry and pharmacognosy of this plant so the basic aim of the study is to analyze pharmacognostic features of dried leaves of Anemone rupicola Camb. Morphology was studied by using the features like margins, shape, length, width, surface and so forth. For anatomical examination leaves were preserved in formalin acetic alcohol (FAA) and cutting the thin section of leaves and petiole with razor blade. Macroscopic characters of powdered drug were evaluated through organoleptic method. Qualitative phytochemical analysis was done by adopting the standard procedures. The antimicrobial activity of methanolic extract of Anemone rupicola Camb. was performed by Agar well diffusion method. The powder microscopic study showed epidermal cells, trichomes, various type of tracheids, pitted vessels, and sclerenchymatous fibers. Transverse cutting of leaves and petiole revealed the presence of different cells such as epidermis, palisade parenchyma, spongy parenchyma cells, aerenchyma, collenchyma, trichomes, and vascular bundles. The investigation of phytochemicals in distilled water, methanol and in ethanol solvent indicated the presence of various secondary compounds such as phenols, saponins, glycosides, alkaloids, tannins, cardiac glycosides, terpenoids, coumarins, and flavonoids. The methanolic extract of Anemone rupicola Camb. has potential as an antimicrobial agent. However, further studies are needed to confirm its efficacy and safety. This study can be used as powerful tool for the identification and authentication of this plant. For the purity and quality control these results will be helpful tool. This will also shed light into new areas where researchers can intervene in developing new drugs for future use.

RESUMO

Cardiovascular diseases (CVDs) are considered as the leading cause of death worldwide. CVD continues to be a major cause of death and morbidity despite significant improvements in its detection and treatment. Therefore, it is strategically important to be able to precisely characterize an individual's sensitivity to certain illnesses. The discovery of genes linked to cardiovascular illnesses has benefited from linkage analysis and genome-wide association research. The last 20 years have seen significant advancements in the field of molecular genetics, particularly with the development of new tools like genome-wide association studies. In this article we explore the profound impact of genetic variations on disease development, prognosis, and therapeutic responses. And the significance of genetics in cardiovascular risk assessment and the ever-evolving realm of genetic testing, offering insights into the potential for personalized medicine in this domain. Embracing the future of cardiovascular care, the article explores the implications of pharmacogenomics for tailored treatments, the promise of emerging technologies in cardiovascular genetics and therapies, including the transformative influence of nanotechnology. Furthermore, it delves into the exciting frontiers of gene editing, such as CRISPR/Cas9, as a novel approach to combat cardiovascular diseases. And also explore the potential of stem cell therapy and regenerative medicine, providing a holistic view of the dynamic landscape of cardiovascular genomics and its transformative potential for the field of cardiovascular medicine.

RESUMO

Paracetamol is a commonly used analgesic and antipyretic drug, but at a high dose level, it leads to deleterious side effects. The need to investigate new hepatoprotective drugs is driven by the lack of safety and efficiency of existing medications. A newly synthesized compound 2', 3'-dihydroxybenzylidene (DHB) was evaluated in the present study for its antioxidant, hepatoprotective and nephroprotective potential compared to ascorbic acid in paracetamol intoxicated rats. DHB and ascorbic acid were evaluated against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) for assessment of the antioxidant potential. Male albino rats (n = 20) were categorized into 5 groups with 4 rats each and the test compounds were administered for 14 days consecutively. On day 15th, the rats were anesthetized, and blood was collected through heart puncture for the evaluation of hematological and serological parameters. Subsequently, the rats were dissected for the histopathology of liver and kidney. Alanine Transaminase (ALT), Alkaline Phosphatase (ALP), Serum Bilirubin (SBR), Cholesterol level and Renal Function Tests (RFTs) showed a substantial increase in the paracetamol treated group. Healing in liver and kidney tissues was observed in the DHB treated groups compared to paracetamol intoxicated group. The hemoglobin (HB), mean corpuscular hemoglobin (MCH), RBCs and mean corpuscular hemoglobin concentration (MCHC) were found significantly elevated while the total leukocytes count (TLC), platelets (PLT) and neutrophils significantly decreased in the DHB treated group compared to the paracetamol intoxicated group. It is concluded that DHB possesses antioxidant, hepatoprotective, nephroprotective, and anti-inflammatory potential against paracetamol induced hepatotoxicity and nephrotoxicity in rats.

RESUMO

Nanotechnology has attracted the attention of researchers from different scientific fields because of the escalated properties of nanomaterials (NMs) compared with the properties of macromolecules. NMs can be prepared through different approaches involving physical and chemical methods. The development of NMs through plant-based green chemistry approaches is more advantageous than other methods from the perspectives of environmental safety, animal, and human health. The biomolecules and metabolites of plants act as reducing and capping agents for the synthesis of metallic green NMs. Plant-based synthesis is a preferred approach as it is not only cost-effective, easy, safe, clean, and eco-friendly but also provides pure NMs in high yield. Since NMs have antimicrobial and antioxidant potential, green NMs synthesized from plants can be used for a variety of biomedical and environmental remediation applications. Past studies have focused mainly on the overall biogenic synthesis of individual or combinations of metallic NMs and their oxides from different biological sources, including microorganisms and biomolecules. Moreover, from the viewpoint of biomedical applications, the literature is mainly focusing on synthetic NMs. Herein, we discuss the extraction of green molecules and recent developments in the synthesis of different plant-based metallic NMs, including silver, gold, platinum, palladium, copper, zinc, iron, and carbon. Apart from the biomedical applications of metallic NMs, including antimicrobial, anticancer, diagnostic, drug delivery, tissue engineering, and regenerative medicine applications, their environmental remediation potential is also discussed. Furthermore, safety concerns and safety regulations pertaining to green NMs are also discussed.

RESUMO

This study describes the fabrication of chemically crosslinked pectin-based LA-co-MAA hydrogels through free radical polymerization technique for the colonic delivery of oxaliplatin. Methylene bisacrylamide was used as a crosslinking agent and ammonium persulfate as an initiator. The successful fabrication and drug loading were confirmed through Fourier transform infrared spectroscopy (FTIR). The thermal investigations through differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) suggested the higher thermal stability of the unloaded and OXP-loaded formulations as compared to the raw materials. X-ray diffraction (XRD) analysis showed a decrease in crystallinity after crosslinking. The swelling, drug loading, and drug release were increased with an increase in the concentration of pectin and lactic acid (LA) while methacrylic acid (MAA) displayed an inverse behavior. The in-vitro biodegradability was evaluated against lysozyme and collagenase. The results showed that the hydrogels were stable against blank PBS as compared to lysozyme and collagenase. MTT-assay proved that the blank hydrogels were cytocompatible while free OXP and OXP-loaded hydrogels displayed dose-dependent effect against Vero, MCF-7, and HCT-116 cell lines. The oral tolerability study in rabbits confirmed that the hydrogel dispersion was well-tolerable up to 3650 mg/kg of body weight without causing any histopathological or hematological changes when compared with the control group.

RESUMO

BACKGROUND: Almost every region of Pakistan is stacked with a large number of medicinal plants. Due to high cost and unavailability of allopathic medicines for the neurological diseases, especially in rural areas, traditional healers prescribe phytotherapy for various neurological diseases like epilepsy, depression, anxiety, insomnia, Alzheimer, and migraine. Such treatments are considered to be most effective by the native people. METHODS: The data was collected from articles published on medicinal plants of various districts of Pakistan, using article search engines like Medline, Pubmed, Web of Science, Science Direct, and Google Scholar. Also, information regarding various neurological uses and mode of applications of medicinal plants was obtained from traditional healers, folk medicine users, and local elderly people having knowledge of medicinal plants. RESULTS: A total of 54 families were found to be used in various neurological diseases, of which the highest use was of Solanaceae (22.22%), Asteraceae (12.96%), Lamiaceae, Papaveraceae, and Poaceae, 9% each, and Caprifoliaceae, Cucurbitaceae, Rhamnaceae, and Rosaceae, 5.5% each. According to districts, 15% of plants that were effective in neurological affections were found in Bahawalpur, 11% in Swat, 8% in Muzaffarabad, 7% in Malakand, and 6% in Bahawalnagar, Dir, Gilgat, and Sarghoda each, with 5% in Dera ghazi khan and Jhelum each. According to the plant's habit, out of total of 103 plants, 61.15% were found to be herbs, 22.33% trees, 11.65% shrubs, and 4.85% climbers. According to the part used of plant, whole plant, leaves, fruits, roots, seeds, and flowers were found to be used 32.03%, 24.27%, 20.38%, 16.50%, 13.59%, and 11.65%, respectively. According to disease's types, 45.63% were found to be effective in insomnia, 31.06% in epilepsy 12.62% in depression, 6.80% in anxiety, 7.77% in hysteria, and 5.88% in migraine. CONCLUSION: Taking into consideration this useful knowledge on medicinal properties of the plants for curing neurologic diseases, it is believed that research in areas of ethnomedicine and ethnopharmacology can bring auspicious results that have potential of adding value to the very rich natural resources of Pakistan. This study will help all the researchers from diverse backgrounds working on plants based medicine for neurological diseases.

RESUMO

BACKGROUND AND OBJECTIVE: Chronic obstructive pulmonary disease (COPD) is characterized by chronic incompletely reversible poor airflow and air trapping and usually this debilitating disorder limits the outside activities of the patients depriving them of sunlight which is a rich source of Vitamin D. The objective of this study was to determine the effect of vitamin D supplementation in reducing number of acute exacerbation in COPD patients. METHODS: This randomized control trial was conducted at East Medical Ward Mayo Hospital Lahore from January to December 2015 as exacerbations of COPD are season dependent. Diagnosis was confirmed by performing Pulmonary Function Tests (PFTs). Basic demographical information was obtained and baseline PFTs of the patient was done. Only Group A patients was treated with oral vitamin D intake of 2000 IU daily for 6 months. Vitamin D level was measured at 0, 2, 4, and 6 months and exacerbation of COPD, FEV1 and FVC was measured weekly. Both the groups were given standard treatment for exacerbation of COPD. Spirometry was repeated at each visit. Blood samples were collected every 2 months for vitamin D. Supplementation was stopped if vitamin D level exceeded 100ng/ml. RESULTS: The mean age of the patients was 46.28±8.83 years, the male to female ratio was 1.8:1. The mean 25(OH) level at baseline was 24.08±2.58 and at 6th month was 29.60±8.74. The mean FVC at baseline was 77.83±5.49 and at 6th month was 91.34±5.52. The exacerbation at baseline was present in all 120(100%) patients and at 6th month was reduced to 4(3.3%). CONCLUSION: Vitamin D supplementation has significant effect in reducing number of acute exacerbation in COPD patients when it is given for prolonged period.
