Saraca indica
Medicinal plants are used as a complementary and alternative medicine in treatment of various diseases including cancer worldwide, because of their ease of accessibility and cost effectiveness. Multicomposed mixture of compounds present in a plant extract has synergistic activity, increases the therapeutic potential many folds, compensates toxicity, and increases bioavailability. Saraca indica (family Caesalpiniaceae) is one of the most ancient sacred plants with medicinal properties, exhibiting a number of pharmacological effects. Antioxidant, antibreast cancer activity and toxicological evaluation of Saraca indica bark extract (SIE) were carried out in the present study. The results of the study indicated that this herbal preparation has antioxidant and antibreast cancer activity. Toxicological studies suggest that SIE is safer to use and may have a potential to be used as complementary and alternative medicine for breast cancer therapy
Strong impact of TGF-β1 gene polymorphisms on breast cancer risk in Indian women: a case-control and population-based study
Introduction: TGF-β1 is a multi-functional cytokine that plays an important role in breast carcinogenesis. Critical role of TGF-β1 signaling in breast cancer progression is well documented. Some TGF-β1 polymorphisms influence its expression; however, their impact on breast cancer risk is not clear. Methods: We analyzed 1222 samples in a candidate gene-based genetic association study on two distantly located and ethnically divergent case-control groups of Indian women, followed by a population-based genetic epidemiology study analyzing these polymorphisms in other Indian populations. The c.29C>T (Pro10Leu, rs1982073 or rs1800470) and c.74G>C (Arg25Pro, rs1800471) polymorphisms in the TGF-β1 gene were analyzed using direct DNA sequencing, and peripheral level of TGF-β1 were measured by ELISA. Results: c.29C>T substitution increased breast cancer risk, irrespective of ethnicity and menopausal status. On the other hand, c.74G>C substitution reduced breast cancer risk significantly in the north Indian group (p  =  0.0005) and only in the pre-menopausal women. The protective effect of c.74G>C polymorphism may be ethnicity-specific, as no association was seen in south Indian group. The polymorphic status of c.29C>T was comparable among Indo-Europeans, Dravidians and Tibeto-Burmans. Interestingly, we found that Tibeto-Burmans lack polymorphism at c.74G>C locus as true for the Chinese populations. However, the Brahmins of Nepal (Indo-Europeans) showed polymorphism in 2.08% of alleles. Mean TGF-β1 was significantly elevated in patients in comparison to controls (p<0.001). Conclusion: c.29C>T and c.74G>C polymorphisms in the TGF-β1 gene significantly affect breast cancer risk, which correlates with elevated TGF-β1 level in the patients. The c.29C>T locus is polymorphic across ethnically different populations, but c.74G>C locus is monomorphic in Tibeto-Burmans and polymorphic in other Indian populations

In vitro physicochemical characterization of nanocarriers: a road to optimization
Today's drug delivery scientists and pharmaceutical technologists own unprecedented variety of characterization techniques at their disposal not only to assign precise numerical values to the particle parameters but also to probe their developmental phases as well as their internal environment. Therefore, mechanistic understanding of structure-function relationships of nanotherapeutic systems seems to be a dynamic avowal considering the optimization of final nanoformulation system intended for biodistribution and targeting. This chapter aims to decipher the key in vitro physicochemical parameters in dry state, liquid state, as well as in both dry and liquid states, with the perspective of nanoparticle technology, and the diverse physical and experimental means in which these parameters can be demarcated. Further, an attempt has been made to introduce some best suited specialized techniques that enable to expand the accessible range of information to gain deeper insights into specific nanoplatform properties

Prevalence and Factors Associated with Impairment in Intrinsic Capacity among Community-Dwelling Older Adults: An Observational Study from South India
Background. Intrinsic capacity (IC) is conceptualized by World Health Organization (WHO) with a focus on healthy aging. Identifying impairment could help in making a person-centred plan for the care of older adults. Objectives. Establish the prevalence of IC among community-dwelling older adults age >60, the prevalence of impairment in each domain, and identify factors associated with an impairment in IC. Methods. This cross-sectional observational study in the community setting included 1000 older adults aged 60 years and above in two-year study period. The 6 domains of IC including cognition, locomotor capacity, psychological, vitality, hearing, and vision were derived from the comprehensive geriatric assessment. The IC composite score was calculated based on these domains, and a higher IC score indicated greater IC. Results. During the study period, 1000 older adults, with the median age of 66.5 (IQR-63-73) were included, and 629 (62.9%) were women. Only in 157 (15.7%) community-dwelling older adults, all 6 domains were intact. Impairment in one, two, and three domains was seen in 442 (42.2%), 305 (30.5%), and 91 (9.1%), respectively. The most prevalent impaired domain was locomotor (593, 59.3%), followed by vision (441, 44.1%), hearing (193, 19.3%), cognition (106, 10.6%), mood (38, 3.8%), and vitality (37, 3.7%). The factors associated with lower IC included increasing age (β-coefficient −0.01, 95% CI: −0.02 to −0.01, p value = 0.002), impaired activities of daily living (β-coefficient −0.13, 95% CI: −0.49 to −0.18, p value <0.001), and chronic neurologic illness (β-coefficient −0.10, 95% CI: −0.77 to −0.18, p value = 0.001). Conclusions. In conclusion, we found that impairment in IC was frequent in community-dwelling older adults, and it is associated with age, presence of chronic neurologic illness, and declining functionality. The adoption of IC should be seen as an opportunity to disseminate geriatric care in our healthcare systems which lack the necessary attention to the needs of older persons

Hemorrhagic reversible cerebral vasoconstriction syndrome: A retrospective observational study
Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by recurrent thunderclap headaches associated with segmental vasoconstriction of cerebral arteries, which may result in intracranial hemorrhage (ICH). There is a lack of contemporary data available regarding the ICH burden in RCVS cohort. Our aim of the study is to assess the ICH burden, associated risk factors, and discharge outcome of ICH in patients with RCVS.
All patients diagnosed with RCVS in the 2016 Nationwide Readmission Database were identified using ICD-10 code after excluding patients with the concurrent diagnosis of primary angiitis. ICH was defined as both intraparenchymal (IPH), subarachnoid hemorrhage (SAH), and subdural hematoma (SDH). Categorical and continuous variables were assessed by the Rao-Scott Chi-square test and the Wilcoxon signed-rank sum test respectively. We used a multivariable survey-weighted logistic model to determine the association between ICH and RCVS patient-level characteristics.
A total of 799 patients were identified with RCVS. Total hospitalization of ICH was 43.4% [(95% CI 36.4-50.4%); (n = 346)] including SAH 35.9% [(95% CI 29.7-42.1%); (n = 287)], IPH 13.1% [(95% CI 9.5-16.7%); (n = 105)] and SDH 3.6% [(95% CI 1.5-5.6%); (n = 28)]. Patients with hemorrhagic RCVS (H-RCVS) had a mean age (years ± SE) of 47.4 ± 1.1 vs. 45.5 ± 1.2 years in R-RCVS (p = 0.247); and were predominantly female (84.0% vs. 68.8%; p = 0.001); with longer inpatient stays (10.9 vs. 6.8 days; p = 0.016); and a higher inpatient cost (21,350; p  64 years) 3.72 (CI: 1.15-12.03; p = 0.029). About 67.0% of all H-RCVS patients were discharged home, with no observed inpatient mortality.
Intracerebral hemorrhage is the most common vascular complication in hospitalized RCVS patients, resulting in longer hospitalizations with more invasive procedures and higher healthcare expenditure. However, overall outcomes are excellent regardless of types of ICH, with no inpatient mortality observed in patients with hemorrhagic RCVS. Female sex and middle to older age-group are associated with higher odds of ICH
