    Abstract Background: Bronchial asthma is a common disease in childhood. Vitamin D deficiency is a common unidentified nutritional deficiency. In spite of high prevalence, an association between the two has not been well understood.
    Objectives: Our study aimed to determine serum Vitamin D levels among asthmatic children and its association with clinical severity and level of control.
    Methods: A hospital-based cross-sectional study was conducted from 2017 to 2019 where 64 recurrent wheezers, classified into 6-15 years and the under 5 wheezers as per Global Initiative for Asthma guidelines, were included. The group of asthmatic children was comparable with respect to their demographic profiles with good adherence and proper inhaler use. Serum Vitamin D levels were estimated using an enzyme-linked immunosorbent assay and classified using the US Endocrine Society classification. Association between Vitamin D status and outcome variables was analyzed using Chi-square test, Fisher's exact test, unpaired t-test, and ANOVA.
    Results: Among the 64 wheezers, 29 (45.3%) had intermittent symptoms and 35 (54.7%) had persistent symptoms. Mean Vitamin D levels in the entire study population were in deficiency range (18.96 ng/ml ± 2.23). Persistent asthmatics had significantly lower Vitamin D levels (13.75 ng/ml) as compared to intermittent asthmatics (28.52 ng/ml). Those asthmatics who had hypovitaminosis D had higher rates of hospitalization (P = 0.048), increased use of rescue medications (P = 0.008), and poor symptom control (P = 0.001).
    Conclusions: Asthmatic children had a higher incidence of reduced Vitamin D levels showing a statistically significant association. There is also a significant association between Vitamin D level and poor symptom control, hospitalization for exacerbations, and requirement of rescue medication in asthmatic children.

    Abstract Alzheimer's disease (AD) is one of the major devastating neurodegenerative disorders associated with the gradual decline of an individual's memory, cognition, and ability to carry out day-to-day activities. In the present study, the neuroprotective ability of α-bisabolol β-d-fucopyranoside (ABFP) was assessed via measurement of antioxidant parameters like lipid peroxidation, glutathione peroxidation, glutathione, protein carbonyl content assays, and caspase-3 activity estimation. Moreover, the acute toxicity of ABFP was estimated in the zebrafish larval model. The results showed that ABFP exhibits little to no toxicity at lower concentrations in the acute toxicity test. ABFP-pretreated and scopolamine-exposed fish exhibited more exploratory behavior in the behavior assay than scopolamine-only induced groups. Additionally, the results of antioxidant enzyme assays revealed reduced oxidative stress and damage in ABFP-treated fish, while enzyme activity experiments carried out with brain homogenate from ABFP-treated fish showed decreased acetylcholinesterase enzyme activity. Overall, it can be concluded that ABFP has the potential to be a promising agent for the treatment of AD in the future.

    Abstract Abstract Background Vitamin D deficiency is common among post-menopausal women and it is important to treat vitamin D deficiency to prevent falls and fractures in patients with osteoporosis. Few studies examined the prevalence of vitamin D deficiency in general population of Sri Lanka but no studies to date done among post-menopausal women with osteoporosis in Sri Lanka. This is the first study in Sri Lanka of such kind conducted to evaluate the serum vitamin D levels among postmenopausal women. Methods Cross-sectional study was conducted at the Endocrine Unit, Teaching Hospital Jaffna from January to December 2018. During this period 105 postmenopausal women who registered for bone density assessment were recruited to the study. Data collection was done by investigators and blood sample was taken from each participant by registered nurses and total 25-Hydroxy Vitamin D level (25(OH)-Vit D) was measured by competitive immunoassay with enhanced chemiluminiscence technique, levels were categorized and analysis was done using SPSS 26. Results Mean age of 105 postmenopausal women was 67.7 with minimum 33 and maximum 84 years. Mean total 25(OH)-Vit D was 27.5 (range11.7–52.5 ng/mL). 25(OH)-Vit D levels were adequate in only 36.2% (95%CI: 27–45), 44% had insufficient levels and deficiency was present in 19% (95%CI: 12–27) of postmenopausal women. Among total study participants 20% were vegetarian, 53, 76.2 and 64.8% were consuming milk, fish and egg respectively and 71.4% reported adequate level of sun exposure (> 30 min/day). Commonly reported vitamin D deficiency symptoms include paraesthesia (57.1%), bone-pain (55.2%), easy fatigability (54.3%), malaise (51.4%), muscle cramps (43.8%) and proximal myopathy (40.0%). Nevertheless, comparison of musculoskeletal symptoms between group with sufficient level and group with insufficient and deficient level showed no significant difference (P > 0.05). Among 71 participants (66.7%) who completed bone density assessment, 38% (95%CI: 27–49) showed osteoporosis. Vertebral ...

    Abstract β-amyloid (Aβ)₂₅₋₃₅ peptide-induced oxidative stress is one of the primary reasons for the development of Alzheimer’s disease (AD). In the present study, α-bisabolol β-D-fucopyranoside (ABFP) was evaluated for its protective effect against β-amyloid (Aβ)₂₅₋₃₅ peptide-induced toxicity in Neuro-2a cells. The results of the current study revealed that ABFP inhibits acetylcholinesterase, apart from reducing the formation of lipid peroxides, protein carbonyls, and nitric oxides in Neuro-2a cells during the treatment of β-amyloid (Aβ)₂₅₋₃₅ peptide. Additionally, ABFP effectively prevented the mitochondrial membrane damage induced by the β-amyloid (Aβ)₂₅₋₃₅ peptide in Neuro-2a cells. Furthermore, ABFP was found to significantly inhibit caspase 3 production in Neuro-2a cells, which was confirmed through AO/EtBr, Annexin-V/FITC, and PI fluorescent microscopic images, indicating that ABFP has anti-apoptotic properties. In addition, ABFP also increased the anti-apoptotic protein expression and protected the Neuro-2a cell from β-amyloid (Aβ)₂₅₋₃₅ peptide-induced toxicity. The in silico molecular docking analysis of ABFP with GSK-3beta showed that it was able to bind with Asn 186, Asp 200, and Lys 183 residues of the enzyme. Overall, the results suggest that ABFP acts as a potent drug against oxidative stress-mediated cell death in AD.

    Abstract: ... neuroprotective ability of the sesquiterpene glycoside α-bisabolol β-D-fucopyranoside (ABFP) against multiple ...

    Abstract Alzheimer's disease (AD) is a multifaceted neurodegenerative disorder affecting the elderly people. For the AD treatment, there is inefficiency in the existing medication, as these drugs reduce only the symptoms of the disease. Since multiple pathological proteins are involved in the development of AD, searching for a single molecule targeting multiple AD proteins will be a new strategy for the management of AD. In view of this, the present study was designed to synthesize and evaluate the multifunctional neuroprotective ability of the sesquiterpene glycoside α-bisabolol β-D-fucopyranoside (ABFP) against multiple targets like acetylcholinesterase, oxidative stress and β-amyloid peptide aggregation induced cytotoxicity. In silico computational docking and simulation studies of ABFP with acetylcholinesterase (AChE) showed that it can interact with Asp74 and Thr75 residues of the enzyme. The in vitro studies showed that the compound possess significant ability to inhibit the AChE enzyme apart from exhibiting antioxidant, anti-aggregation and disaggregation properties. In addition, molecular dynamics simulation studies proved that the interacting residue between Aβ peptide and ABFP was found to be involved in Leu34 and Ile31. Furthermore, the compound was able to protect the Neuro2 a cells against Aβ

    Abstract BACKGROUND: Vitamin D deficiency is common among post-menopausal women and it is important to treat vitamin D deficiency to prevent falls and fractures in patients with osteoporosis. Few studies examined the prevalence of vitamin D deficiency in general population of Sri Lanka but no studies to date done among post-menopausal women with osteoporosis in Sri Lanka. This is the first study in Sri Lanka of such kind conducted to evaluate the serum vitamin D levels among postmenopausal women. METHODS: Cross-sectional study was conducted at the Endocrine Unit, Teaching Hospital Jaffna from January to December 2018. During this period 105 postmenopausal women who registered for bone density assessment were recruited to the study. Data collection was done by investigators and blood sample was taken from each participant by registered nurses and total 25-Hydroxy Vitamin D level (25(OH)-Vit D) was measured by competitive immunoassay with enhanced chemiluminiscence technique, levels were categorized and analysis was done using SPSS 26. RESULTS: Mean age of 105 postmenopausal women was 67.7 with minimum 33 and maximum 84 years. Mean total 25(OH)-Vit D was 27.5 (range11.7–52.5 ng/mL). 25(OH)-Vit D levels were adequate in only 36.2% (95%CI: 27–45), 44% had insufficient levels and deficiency was present in 19% (95%CI: 12–27) of postmenopausal women. Among total study participants 20% were vegetarian, 53, 76.2 and 64.8% were consuming milk, fish and egg respectively and 71.4% reported adequate level of sun exposure (> 30 min/day). Commonly reported vitamin D deficiency symptoms include paraesthesia (57.1%), bone-pain (55.2%), easy fatigability (54.3%), malaise (51.4%), muscle cramps (43.8%) and proximal myopathy (40.0%). Nevertheless, comparison of musculoskeletal symptoms between group with sufficient level and group with insufficient and deficient level showed no significant difference (P > 0.05). Among 71 participants (66.7%) who completed bone density assessment, 38% (95%CI: 27–49) showed osteoporosis. Vertebral Z score showed a significant correlation with 25(OH)-Vit D level (r-0.252, P-0.03). CONCLUSION: Prevalence of vitamin D deficiency is relatively high among the post-menopausal women with a provisional diagnosis of osteoporosis. It is essential to consider vitamin D supplementation when initiating treatment for osteoporosis. Hence, Vitamin D testing is desirable in decision making to treat or not to treat.
