ABSTRACT

ABSTRACT Purpose: Ureteropelvic junction obstruction (UPJO) is a prevalent cause of hydronephrosis, especially in young patients. The treatment paradigm for this condition has shifted from open to minimally invasive pyeloplasty. In the present study we describe our initial single centre experience with single port (SP) robot-assisted pyeloplasty (RAP) via periumbilical incision. Material and methods: With the patient in a 60-degree left flank position, the SP system is docked with the Access port (Intuitive Surgical, Sunnyvale, CA, US) placed in a periumbilical 3 cm incision. Robotic instruments are deployed as follows: camera at 12 o'clock, bipolar grasper at 9 o'clock, scissors at 3 o'clock and Cadiere at 6 o'clock. After isolation and identification of the ureter and the ureteropelvic junction (UPJ), the ureter is transected at this level and then spatulated. Anastomosis is carried out by two hemicontinuous running sutures, over a JJ stent. Results: Between 2021 and 2023, a total of 8 SP RAP have been performed at our institution, with a median (interquartile range, IQR) of 23 years (20.5-36.5). Intraoperative outcomes showed a median (IQR) OT of 210.5 minutes (190-240.5) and a median (IQR) estimated blood loss (EBL) of 50 mL (22.5-50). No postoperative complications were encountered, with a median (IQR) length of stay (LOS) of 31 hours (28.5-34). Conclusion: In the present study we evaluated the feasibility and safety of SP RAP. The observed outcomes and potential benefits, combined with the adaptability of the SP platform, hold promising implications for the application of SP system in pyeloplasty treatment.

ABSTRACT

Purpose: To curtail the potential of donor corneal tissue disseminating fungi to the recipient抯 eye, we evaluated the addition of amphotericin B to McCarey?Kaufman (M?K)梒orneal storage medium supplemented with colistin. Methods: Amphotericin B was examined for its ability to inhibit the growth of Candida albicans and Aspergillus flavus using a microbroth dilution test and checkerboard assay in combination with only gentamicin and a combination of colistin, gentamicin, and amphotericin B. The safety on epithelium and endothelium was evaluated by 3?(4,5?dimethylthiazol?2?yl)?2, 5?diphenyltetrazolium bromide (MTT) assay. Results: The minimal inhibitory concentration of gentamicin was found to be >256 ?g/ml against both C. albicans and A. flavus, whereas that of amphotericin B was found to be in a range of 0.25�5 and 1�?g/ml for C. albicans and A. flavus, respectively. According to the checkerboard assay, 80% (4/5) of C. albicans isolates and 100% (5/5) of A. flavus isolates responded synergistically to the combination of amphotericin B and gentamicin, but only 20% (1/5) of C. albicans isolates showed an additive effect. None of the tested isolates displayed antagonism. The combined effect of the three drugs also did not display any antagonistic effect. Additionally, the MTT assay reveals no toxic effect of the antimicrobials used on corneal epithelial and endothelial cells. Conclusion: In vitro experiments demonstrate that amphotericin B is not toxic to either epithelium or endothelium and is a promising additive to the M?K medium supplemented with colistin.

ABSTRACT

Purpose: To document the spectrum and magnitude of eye disorders and visual impairment in the Dongaria—a Particularly Vulnerable Tribal Group in the Rayagada district of Odisha, India. Methods: A door?to?door screening protocol included a record of basic health parameters, visual acuity for distance, and near and flashlight examination of the eyes. Spectacles were dispensed to those who improved; those who failed the screening were referred to fixed (primary and secondary) eye care centers. Results: We examined 89% (n = 9872/11,085) of people who consented for screening. The mean age was 25.5 ± 18.8 years; 55% (n = 5391) were female; 13.8% (n = 1361) were under?five children, and 39% (n = 3884) were 6 to 16 years. 86% (n = 8515) were illiterate. 12.4% (n = 1224) were visually impaired, of which 9.9% had early moderate VI, and 2.5% had severe VI and blindness. Uncorrected refractive error was detected in 7.5% (n = 744) and cataracts in 7.6% (n = 754); among the adults, 41.5% (n = 924/2227) had presbyopia. In children, 20% (n = 790) had vitamin A deficiency, 17% (n = 234) had global acute malnutrition, and 18% (n = 244) were stunted for their age. Almost two?thirds (62%, n = 6144) confirmed habitual intake of alcohol, and 4% (n = 389) of adults had essential hypertension. Following the screening, 43.5% (n = 837) of referred patients reported to the fixed centers, and 55% (134/243) of people advised underwent cataract surgery. Spectacles were dispensed to 1496 individuals. Conclusion: Visual impairment and malnutrition are high in Dongaria indigenous community. Permanent health facilities and advocacy would improve this community’s health and health?seeking behavior.

ABSTRACT

Metastasis accounts for the most common tumor of the central nervous system (CNS) in adults. Renal cell carcinoma (RCC) is one of the common carcinoma showing brain metastasis, with a predilection for clear cell variant. Chromophobe RCC (ChRCC) in contrast to clear cell RCC shows far less common distant metastasis. When they metastasize, commonly involve the liver, lungs, and lymph nodes. ChRCC metastasizing to the brain is extremely rare. Isolated brain metastasis from RCCs is also uncommon. We report an unusual case of a 54-year-old woman with ChRCC with isolated metastasis to the brain, 2 years after radical nephrectomy for renal mass.

ABSTRACT

SMARCB1 (INI-1)-deficient sinonasal carcinoma is a rare, poorly differentiated carcinoma defined by complete loss of tumor suppressor gene SMARCB1 (INI-1) within the neoplastic cell nuclei demonstrated by the immunohistochemical stain. SMARCB1 (INI-1) gene inactivation has been implicated in the pathogenesis of a diverse group of malignant neoplasms that tend to share “rhabdoid” morphology. SMARCB1 (INI-1)-deficient sinonasal carcinoma was first reported by Agaimy et al. in 2014. These tumors are often basaloid with focal rhabdoid differentiation, prominent necrosis, increased mitotic activity, and aggressive behavior. Other than being INI-1 and NUT negative, they are positive for pancytokeratin and express variable immunoreactivity for squamous markers like p63 and neuroendocrine markers like synaptophysin. Most patients present with locally advanced disease and hence a combination of chemotherapy, radiotherapy, and surgery is usually recommended.

ABSTRACT

Hypertension is an important worldwide public-health challenge and it is accountable for 7% of Disability Ad-justed Life Years (DALY) loss, and by the end of 2025 about 29% of world’s population is likely to suffer from hypertension. Tribal population constitute about 8% of the total population in India. Among tribal population, study on hypertension will provide an interesting outcome because studies across the world have shown a lower prevalence. The objective of the study was to estimate the pooled prevalence of hypertension among adult tribal populations in India and also to analyse the possible sources of heterogeneity in the estimate. A systematic search was performed in PubMed, Google scholar, Scopus, Embase MEDLINE, and journals for arti-cles published between 2001 and 2020. This is a systematic review and meta-analysis done on hypertension among tribal populations of India. Three authors independently reviewed the articles, performed quality as-sessment and data was extracted. Pooled estimate of hypertension was calculated. Subgroup analyses was performed. A total of 26 articles with a total number of subjects of 75,543 were included in the study. The pooled estimate of hypertension prevalence was 25.1% (95% CI: 24.7, 25.4). There was significant heteroge-neity among the studies (I2 = 98.2 and Q = 1289.37). It is essential to conduct larger cohort studies and ran-domised controlled trials to determine the causes of the increased prevalence of hypertension among the tribal population. The prevalence of hypertension among tribal population are essential as a source of prima-ry information and for rational planning of health services and will help public-health policy-makers to assign sufficient priority and resources for its management and prevention.

ABSTRACT

Dry Eye Module (DEM), a software application, was developed to facilitate the streamlining of dry eye evaluation and documentation, to unify diagnostic jargon, and to analyze data input to generate a dry eye diagnostic report. This diagnostic report generated is based on the current understanding of dry eye diagnostic algorithms (Dry Eye Workshop 2 [DEWS2]/Asia Dry Eye Society [ADES]). Apart from its plausible role in aiding unprecedented multicentric dry eye demographic data collection, the application software can generate a customized referral letter to the rheumatologist, highlighting the salient ophthalmic features to be shared. DEM uses schematic illustrations to depict eyelid, conjunctival, and corneal parameters that impact the ocular surface in dry eyes that can be captured and compared during serial visits. Furthermore, DEM displays a symptom sign trend chart that graphically represents improvement/stability or worsening of the subjective and objective dry eye status. DEM can generate a curated prescription using preloaded advice templates. DEM includes facility for state-of-the-art advanced dry eye diagnostic reporting for super specialty use. The addition of DEM to the dry eye diagnostic armamentarium would help bridge the current unmet needs of dry eye evaluation. These are lack of uniform reporting, lack of multicentric data on a unified platform, the inability to ensure complete evaluation, inability to avoid lacunae during follow-up visits, and the lack of a simple patient-ophthalmologist and an ophthalmologist–rheumatologist interface.

ABSTRACT

Background: Dermoscopy is useful in the diagnosis of basal cell carcinoma (BCC). However, most descriptions of the dermoscopic features of BCCs are in Caucasians (skin types I-III) and there is a paucity of data in dark-skinned Indian patients. Aims: The aim of this study was to describe the various dermoscopic features of BCC in dark-skinned patients from South India and correlate these with the histopathologic subtypes. Methods: A retrospective observational study of biopsy-proven cases of BCC was conducted at a tertiary care center in South India using nonpolarized contact dermoscopy. Results: Sixty BCCs in 35 patients predominantly of skin phototypes IV or V were studied. These included 32 nodular, 27 superficial and 1 infiltrative type of BCC. The most common dermoscopic features noted were maple leaf-like areas (61.7%), blue-white veils (53.4%), ulceration (48.4%) and short fine telangiectases (46.7%). Ulceration, blue-white veils and arborizing vessels were significantly associated with nodular BCCs, while maple leaf-like areas, red-white structureless areas, multiple small erosions and spoke wheel areas were noted with superficial BCCs. Limitations: The limitations of this study include its retrospective nature, the use of only nonpolarized light for examination, the lack of other histopathological variants of BCC as well as the lack of a comparison group. Conclusion: We report a dermoscopic study of BCC in dark-skinned patients from Puducherry, South India. The blue-white veil was observed in half of the patients and was significantly associated with nodular BCCs. The addition of the blue-white veil to the diagnostic criteria for pigmented BCC could improve the diagnostic accuracy of dermoscopy in Indian patients.

ABSTRACT

Purpose: To assess the incidence, visual impairment, and blindness due to retinitis pigmentosa (RP) in a rural southern Indian cohort. Methods: This is a population?based longitudinal cohort study of participants with RP from the Andhra Pradesh Eye Disease Study (APEDS) cohorts I and III, respectively. The study included participants with RP of APEDS I who were followed until APEDS III. Their demographic data along with ocular features, fundus photographs, and visual fields (Humphrey) were collected. Descriptive statistics using mean ± standard deviation with interquartile range (IQR) were calculated. The main outcome measures were RP incidence, visual impairment, and blindness as per the World Health Organization (WHO) definitions. Results: At baseline (APEDS I), 7771 participants residing in three rural areas were examined. There were nine participants with RP with a mean age at baseline of 47.33 ± 10.89 years (IQR: 39–55). There was a male preponderance (6:3), and the mean best?corrected visual acuity (BCVA) of 18 eyes from nine participants with RP was 1.2 ± 0.72 logarithm of minimum angle of resolution (logMAR; IQR: 0.7–1.6). Over a mean follow?up duration of 15 years, 5395/7771 (69.4%) were re?examined, which included seven RP participants from APEDS 1. Additionally, two new participants with RP were identified; so, the overall incidence was 370/ million in 15 years (24.7/million per year). The mean BCVA of 14 eyes of seven participants with RP who were re?examined in APEDS III was 2.17 ± 0.56 logMAR (IQR: 1.8–2.6), and five of these seven participants with RP developed incident blindness during the follow?up period. Conclusion: RP is a prevalent disease in southern India that warrants appropriate strategies to prevent this condition.

ABSTRACT

Background: Skin lesions are the most common early symptoms of leprosy, often ignored by patients at an early stage and misdiagnosed as other dermatological diseases by healthcare personnel, leading to delay in diagnosis and treatment of leprosy precipitating permanent neurological deficit, deformities and serious disabilities. Aims: The objective is to evaluate the duration of delay and factors responsible for the delay in reporting of patients, among the newly detected leprosy cases (Grade 1 and Grade 2 disability patients). Methods: A case-control study was conducted during 2014–2016 in three major states of India (Delhi, Gujarat and West Bengal) in 140 randomly recruited newly registered adult leprosy patients (aged 18 years and above) with Grade 2/1 disabilities (cases) and 140 Grade 0 disability patients (controls) in each of these Indian states. Results: It is established that the major contributors for the delay in the early diagnosis of leprosy have been patient-related factors. The median patient delay in the three states of Delhi, Gujarat and West Bengal were five months (0.7–1.8), 2.8 months (2–14) and 12 months (2–24), respectively. Limitations: The study design is case-control and has an inbuilt reporting bias due to the retrospective nature of data collection but the data collection was carried with caution to reduce the recall bias. As the study is carried out in three states, generalisation of interpretation was cautiously executed. The matching ratio of cases and controls was 1:1 in this study, but we could not increase the controls due to operational feasibility during the conduct of the study. Conclusion: Patient delay is a crucial factor responsible for the disability among new leprosy cases. A higher patient delay in these three states reflects that the community is not aware about the signs and symptoms of leprosy. Reducing patient delay is very important for reducing disabilities in the newly diagnosed cases.

ABSTRACT

Background: An eight-year-old Ongole cow was brought to the large Gynaecology ward, Department of VGO, NTR College of Veterinary Science, Gannavaram with a history of irregular cloudy vaginal discharge. The local veterinarian did not appreciate the growth of the gravid uterine horn during repeated per-rectal examinations in 30-day intervals. Methods: On rectal examination, the right uterine horn was distended with fluid. On real-time ultrasonography, the ovaries were diagnosed with the presence of large anechoic follicles on both left and right ovaries. The cow was diagnosed as mucometra due to follicular cyst and treated with ovsynch plus CIDR protocol using 20礸 of GnRH and cloprostenol sodium of 500 礸 and CIDR device containing progesterone of 1.9 gms. Results: Re-examination after one month revealed the persistence of cysts on both the ovaries and the distended right uterine horn. Conclusion: The treatment was not successful because of the longstanding follicular cysts and thickening, and unresponsiveness of uterine endometrium. The prognosis of the present case was guarded.

ABSTRACT

Background: A full-term pregnant Ongole cow was presented to the Large Animal Obstetrical Ward with a history of reduced feed intake, dull and ruptured foetal membranes 24 hours before presentation without progress in parturition. The temperature was within the normal physiological range. Per-vaginal examination revealed second-degree cervical dilation, lack of uterine and abdominal contractions and the vaginal discharges were reddish brown and putrid. Methods: The case was diagnosed as secondary uterine inertia and treated with an intracervical application of misoprostol and intravenous calcium therapy. Results: Three hours after the application of misoprostol and calcium therapy, full dilatation of the cervix was achieved to facilitate the delivery of the dead male emphysematous foetus by traction. Uneventful recovery of the dam was noticed. Conclusion: Usage of misoprostol along with CMC massage and calcium therapy resulted in speedy recovery of dystocia suffering with incomplete cervical dilation.

ABSTRACT

Objective: To determine early breastfeeding problems using LATCH tool, and analyze the impact of breastfeeding supportive measures in improving LATCH score. Methods: This prospective study included all inborn term neonates born at our center between September, 2019 and March, 2020. Breastfeeding problems were identified by LATCH score at 6-12h after birth, and were addressed by the study team providing breastfeeding support, education and training to mothers. LATCH scores were reassessed at 24-48h. Results: Among 400 mother-infant dyads, 399 (99.7%) required support to position the neonate, 190 (47.5%) had poor latch and 52 (13%) had nipple problems during initial assessment. Breastfeeding supportive measures improved the LATCH score [median (IQR) 7 (5,8) vs 8 (8,8) at 6-12 and 24-48 hours, respectively; P <0.001], and reduced the number of mothers with LATCH score <8 [288 (72%) vs 63 (15.8%); P <0.001]. Conclusion: LATCH is a comprehensive yet simple tool to identify breastfeeding problems. Given the high incidence of breastfeeding problems during early postpartum period, systematic assessment of breastfeeding related problems using LATCH tool can help timely intervention and improvement in the breastfeeding technique.

ABSTRACT

Purpose: This study was conducted to report on the pattern of spectacles use and compliance among the elderly (aged ?60 years) in homes for the aged in Hyderabad region in Telangana State, India. Methods: Participants were recruited from 41 homes for the aged centres for comprehensive eye health assessments. A questionnaire was used to collect information on current and past use of spectacles, type of spectacles, spectacles provider and amount paid for the spectacles. For those that reported using spectacles in the past, information was collected on the reasons for their discontinuation. Compliance with spectacles use was assessed after eight months of provision of the spectacles. Results: A total of 1182/1513 participants were examined from 41 homes for the aged in Hyderabad, India. The mean age of the participants examined was 75 years (standard deviation (SD): 8.8 years; range: 60–108 years); 764 (64.6%) of them were women and 240 participants (20.3%) had no formal education. The prevalence of spectacles use was 69.9% (95% confidence interval [CI]: 67.1–72.4; n = 825). Bifocals were the most commonly used type of spectacles (86.7%) followed by single vision glasses for distance vision (7.4%). Private eye clinics were the largest service provider (85.5%) followed by local optical outlets (6.9%) and other service providers (7.7%). The prevalence of spectacles compliance was 81.5% (211/259). Conclusion: Use of spectacles and compliance are high among the elderly living in residential care homes in the Hyderabad region. Spectacles use can be further improved by periodic eye assessments along the lines similar to school eye programs, which can immensely benefit this vulnerable, aged population

ABSTRACT

Background & objectives: FOLFIRINOX and gemcitabine plus nab-paclitaxel (GN) are the most commonly used regimens in advanced pancreatic ductal adenocarcinomas (PDACs). As there is limited data on comparison of these two regimens, the present study was aimed to compare survivals and tolerance for both regimens through a match-pair analysis. Methods: The data of 350 patients with metastatic and locally advanced PDAC, treated between January 2013 and December 2019, were retrieved. A 1:1 matching, using age and performance status, without replacement was performed by using nearest neighbour matching method. Results: A total of 260 patients (130 modified FOLFIRINOX and 130 GN) were matched. The median overall survival (OS) was 12.98 months [95% confidence interval (CI) 7.257-8.776 months] in modifications of FOLFIRINOX (mFOLFIRINOX) cohort and 12.06 months (95% CI 6.690-8.88 months) in GN group (P=0.080). The incidence of grade 3 and 4 infections, diarrhoea, oral mucositis, and fatigue was higher with mFOLFIRINOX. Patients who received second line therapy had improved OS as compared to those who did not (14.06 vs. 9.07 months, P<0.001). Interpretation & conclusions: GN and mFOLFIRINOX appear to have similar survival outcomes in an unselected match paired patient population with advanced PDAC. A markedly increased incidence of non-myelosuppressive grade 3 and grade 4 side-effects and lack of survival improvements suggest a need for nuanced use of the mFOLFIRINOX regimen. Administration of second-line chemotherapy improves OS in patients with advanced PDAC.

ABSTRACT

ABSTRACT Objective: To evaluate and compare bite force (BF) in permanent first molars restored with glass ionomer cement (GIC), composite and amalgam, and normal contralateral permanent first molars. Material and Methods: BF was recorded in decayed permanent first molars, which were filled with GIC (n=30), composite (n=30), and amalgam (n=30), and in healthy contralateral first molars (n=90) with Force Transducer Occlusal Force Meter and compared. Results: BF was significantly higher in normal teeth on the contralateral side compared to teeth restored with GIC and composite. However, in patients with amalgam restoration, though it was less compared to that on the contralateral side, it was not statistically significant (p>0.05). Conclusion: Restoring teeth with various filling materials may improve bite force. In the present study, it was found that the teeth restored with amalgam had higher bite forces in comparison to the other restorative materials used. However, it was not comparable to that observed in the normal tooth (control) on the contralateral side.

ABSTRACT

Background: Background: Staphylococcus aureus is a gram-negative bacterium that can build strong biofilms on biotic and abiotic surfaces, quickly acquire drug resistance mechanisms, and cause major issues with the treatment of hospital infections. The creation of new therapeutic options has become important due to the limited supply of new antibacterial medications. One of the main sources of bioactive molecules is medicinal plants, and monolaurin is a naturally occurring substance with a variety of biological functions. In light of this, the goal of this study was to assess monolaurin's antibiofilm activity against S. aureus. Methods: Using the AutoDock programme, a docking study of monolaurin against Clf A (clumping factor A) was carried out, and Pymol software was used to evaluate the generated hydrogen bonds in the docked complex. This study demonstrates the positive potential of monolaurin as an antibacterial product and lends support to upcoming pharmacological research on this molecule with an eye toward its therapeutic use. Results: Research was done to support the theoretical absorption of monolaurin in this work and in silico. It was feasible to forecast if the monolaurin molecule may be produced as a medication based on the values of the physical-chemical parameters evaluated using the online tool Swiss ADME. Conclusion: The compound monolaurin demonstrated good receptor ClfA binding affinity with an estimated binding energy of kcal/mol. Natural anti-staphylococcal chemical monolaurin was used as a possible medicine for treating staphylococcal infections in humans by carrying out drug design studies for S. aureus.

ABSTRACT

Chikungunya means “that which bends up,” indicating severe incapacitating arthritis or polyarthralgia. It is a viral infection caused by the chikungunya virus (CHIK V) belonging to the family Togaviridae and is transmitted by the mosquitoes Aedes aegypti and Aedes albopictus. It is a self-limiting condition with a high fever of up to 40°C (104°F), debilitating arthritis/polyarthralgia, and cutaneous involvement. CHIK V virus affects the joints causing tenosynovitis and enthesopathy presenting as arthralgia. Leprosy is also associated with the loss of sensation, arthritis/arthralgias including involvement of several joints and tenosynovitis specially during reactions. Apart from leprosy, numerous other conditions can present with loss of sensation, which must be ruled out while considering leprosy. We report two patients with chikungunya who presented with a loss of sensation like leprosy

ABSTRACT

Background & objectives: COVID-19 has been a global pandemic since early 2020. It has diverse clinical manifestations, but consistent immunological and metabolic correlates of disease severity and protection are not clear. This study was undertaken to compare seropositivity rate, antibody levels against nucleocapsid and spike proteins, virus neutralization and metabolites between adult and child COVID-19 patients. Methods: Plasma samples from naïve control (n=14) and reverse transcription (RT)-PCR positive COVID-19 participants (n=132) were tested for reactivity with nucleocapsid and spike proteins by ELISA, neutralization of SARS-CoV-2 infectivity in Vero cells and metabolites by 1H nuclear magnetic resonance (NMR) spectroscopy. Results: An ELISA platform was developed using nucleocapsid and spike proteins for COVID-19 serosurvey. The participants showed greater seropositivity for nucleocapsid (72%) than spike (55.3%), and males showed higher seropositivity than females for both the proteins. Antibody levels to both the proteins were higher in intensive care unit (ICU) than ward patients. Children showed lower seropositivity and antibody levels than adults. In contrast to ICU adults (81.3%), ICU children (33.3%) showed lower seropositivity for spike. Notably, the neutralization efficiency correlated with levels of anti-nucleocapsid antibodies. The levels of plasma metabolites were perturbed differentially in COVID-19 patients as compared with the naive controls. Interpretation & conclusions: Our results reflect the complexity of human immune response and metabolome to SARS-CoV-2 infection. While innate and cellular immune responses are likely to be a major determinant of disease severity and protection, antibodies to multiple viral proteins likely affect COVID-19 pathogenesis. In children, not adults, lower seropositivity rate for spike was associated with disease severity

ABSTRACT

Glioblastoma is aggressive brain tumour with poor prognosis with conventional chemotherapy, hence there is need to find alternative targets for developing newer treatment. Advent of new treatment methods involving medicinal plants have shown to reduced Cancer mortalities and prevents development of drug resistance for chemotherapy. Present study aimed at investigates the anti-proliferating activity of two promising medicinal plants, Ocimum sanctum and Centella asiatica. We studied the effect of their plant extract on U87MG Glioblastoma cells proliferation, survival effect and apoptosis. Cytotoxic activity was assessed, after the plant extract treatment on U87MG using MTT assay with dose of 1 mg/mL to 25mg/mL and apoptosis assess was done using Annexin V assay with the three dose (1.5 mg/mL, 2 mg/mL and 2.5 mg/mL). Survivin gene expression was studied using QRT-PCR (Rotar gene Q, Qiagene) has a marker of proliferation. Ocimum sanctum and Centella asiatica treatment of U87MG cells with dosage of 1.5 mg/mL, 2.0 mg/mL, 2.5 mg/mL showed increase in mean apoptotic cells 2.8 %, 4.9%, 10 % and 3.1%, 5.8% and 7.2%, respectively, compared to untreated U87MG cells. Survivin gene analysis of U87MG cells showed down-regulation in gene expression and differences was significant in comparison to untreated control group with both the plant extract, Centella asiatica showed more down-regulation (97% with 2.5 mg/mL) than Ocimum sanctum. Ocimum sanctum and Centella asiatica exhibited promising anti-proliferating activity and induces apoptosis by down regulation of survivin gene expression
