Assessing the Effects of Biostimulant on Tomato Growth, Yield and Quality in Open Field Condition

Aim: This study, conducted at "C" Block Farm, Bidhan Chandra Krishi Viswavidyalaya, Kalyani, Nadia, West Bengal, during the period of 2022–23, explores the impact of biostimulants on the growth, yield, and quality of tomatoes (Lycopersicon esculentum Mill.). The primary objectives include investigating the significant effects of biostimulants and determining the optimal stage for their application, given the current emphasis on sustainable farming practices.Study Design: The experimental design employed Randomized Block Design (RBD) with three replications and eight treatments. Results indicate that biostimulant application, particularly as a foliar spray, significantly enhances crop growth and stimulates reproductive growth in later stages compared to control plants. Notably, the application of Biostimulant (Kazuki Gold)topically at 500 ml/acre during pre-flowering stage and during fruit development stage (T5) significantly registered the highest yield of 751.89 q/ha.Place and Duration of Study: The farm, situated near the Tropic of Cancer, exhibits coordinates of approximately 22.89°N latitude and 88.45°E longitude, with an altitude of around 9.75 m above sea level.Results: The highest lycopene content of 5.08 mg/100gm, which was significantly superior over all the treatments was obtained with the application of Kazuki gold during the two stages of application (i.e. at pre- flowering stages and during fruit development stage). The study also observed substantial impacts on other quality parameters with the application of seaweed extracts, protein hydrolysates, and N-fixing growth promoters during various stages of plant growth.Conclusion: Based on the findings, it can be concluded that Applying KAZUKI GOLD/YOSHI GOLD through foliar spray at a rate of 500ml per acre during the pre-flowering and fruit development stages has demonstrated profitability and advantages, leading to increased yields of high-quality tomato fruits.

Assessing the Growth, Yield, and Quality of Different Varieties of Cherry Tomato (Solanum lycopersicum Mill. Var. Cerasiforme) Under Polyhouse

Aim: Cherry tomatoes (Solanum lycopersicum Mill. var. cerasiforme) are highly favored for their delectable flavor and plentiful small-sized fruits that form clusters on the plant's stems and branches. This study focused on examining the “Assessing the Growth, Yield, and Quality of Different Varieties of Cherry Tomato (Solanum lycopersicum Mill. var. cerasiforme) under Polyhouse”.Study Design: In the first and second years of varietal evaluation, the experiment was set up using a Complete Randomized Block Design (C.R.B.D.) with nine treatments (varieties) and three replications Nine cherry tomato are collected from different sources and the varieties are BSS-834, Nagmani, Nagmoti, Rosa, Sheeja, Laila, Darjeeling Local, Ken and Red Cherry.Place and Duration of Study: The current study was carried out in the naturally ventilated arched sawtooth polyhouse at the Bidhan Chandra Krishi Viswavidyalaya in Mohanpur, Nadia (West Bengal) in the years 2021–2022 and 2022–2023.Methodology: The dimensions of the experimental plot were 2.5 m x 1 m2, with a row spacing of 50 cm and a plant spacing of 50 cm. The tests used the ridge bed approach, with two rows per bed. During the two years of the experiment, a number of significant characteristics were noted, such as the number of primary branches and the plant height (in centimeters) related to vegetative development. For every replication, a statistical analysis of the mean values was performed.Results: Out of all the cultivars evaluated, BSS-834 and Laila showed the best yield and yield-related attributes.Conclusion: It is therefore advised to cultivate these two excellent kinds, "BSS-834" and "Laila," in light of the findings.

Factors limiting the Northeast Indian elderly population from seeking cataract surgical treatment: Evidence from Kolasib district, Mizoram, India

Purpose: Reliable data on the barriers to the uptake of cataract surgical services in the Northeast Indian states are scanty. The purpose of this study was to assess the barriers to uptake of cataract surgical services among elderly patients and suggest appropriate strategies to reduce these. Methods: A cross-sectional study was conducted among patients who failed to avail cataract surgical services, 6–12 months' postinitial diagnosis at a community eye health camp. Validated questionnaire was used to collect information through face-to-face interviews at the residence of the participants. Descriptive statistics and Chi-square tests were conducted to assess the association between the barriers quoted and sociodemographic variables. Results: A total of 140 (89.2%) individuals participated in the study, of whom 56 (40%) were aged between 71 and 80 years. The median age for men and women was 73.5 and 72.5 years, respectively. About 57% of participants were female patients. A total of 66 (47.1%) participants had borderline visual acuity followed by those with poor vision (41.4%, n = 58). “Bad roads/difficult terrain” (P = 0.009), “witnessed bad surgical outcomes in others” and “did not feel important” (P < 0.024), “poor overall health status” (P < 0.001), “lack of information” (P = 0.025) and “no escort” (P = 0.025) were significant barriers reported by this population. Conclusion: Most of the barriers reported in this study seem to be endogenous in nature and appear to be within the purview of the local eye care service provider to remedy. Counseling and targeted awareness and information, education, and communication strategies could nullify many of the barriers reported in this study.

Serum lipoprotein ratios as markers of insulin resistance: A study among non-diabetic acute coronary syndrome patients with impaired fasting glucose.

Background & objectives: Recent data suggest that insulin resistance can predict cardiovascular disease independently of the other risk factors, such as hypertension, visceral obesity or dyslipidaemia. However, the majority of available methods to evaluate insulin resistance are complicated to operate, expensive, and time consuming. This study was undertaken to assess whether serum lipoprotein ratios could predict insulin resistance in non-diabetic acute coronary syndrome (ACS) patients. Methods: Ninety non-diabetic patients with impaired fasting glucose admitted with a diagnosis of ACS were included in the study. At the time of admission fasting glucose and insulin concentrations were measured. The homeostatic model assessment-insulin resistance (HOMA-IR) was used for insulin resistance. The fasting serum total cholesterol (TC), triglycerides (TG) and high density lipoprotein cholesterol (HDL-C) levels were checked, and then TC/HDL-C and TG/HDL-C ratios were calculated. The areas under the curves (AUC) of the receiver operating characteristic (ROC) curves were used to compare the power of these serum lipoprotein ratios as markers. Results: Lipoprotein ratios were significantly higher in patients with HOMA-IR index > 2.5 as compared to patients with index <2.5 (P < 0.05). Both TG/HDL-C and TC/HDL-C ratios were significantly correlated with HOMA-IR (P<0.05). The area under the ROC curve of the TG/HDL-C and TC/HDL-C ratio for predicting insulin resistance was 0.80 (95% CI, 0.67 to 0.93), 0.78 (95% CI, 0.65 to 0.91), respectively. Interpretation & conclusions: The findings of this study demonstrate that serum lipoprotein ratios can provide a simple means of identifying insulin resistance and can be used as markers of insulin resistance and cardiovascular diseases risk in adult non-diabetic patients.

Homozygous Familial Hypercholesterolaemia with Valvular Aortic Stenosis and Significant Coronary Artery Disease: A Case Report.

Homozygous Familial Hypercholesterolaemia is a genetic disorder which usually presents with early cardiovascular disease ranging from premature ischaemic disease, including myocardial infarction to aortic root stenosis. A 21 year old Bangladeshi male presented with exertional chest pain and breathlessness. He was diagnosed as a case of Homozygous Familial Hypercholesterolaemia. His angina symptoms were due to underlying valvular aortic stenosis which is a rare presentation of Homozygous Familial Hypercholesterolaemia.

Stereotactic body radiotherapy in early stage non-small cell lung cancer: First experience from an Indian Centre.

BACKGROUND: Surgery is the standard of care for early stage (T1-2, N0, M0) non-small cell lung cancer. A considerable number of these patients are ineligible for surgery due to age and comorbidities. Hypo fractionated high-dose stereotactic body radiotherapy (SBRT) is being performed for these group of patients. There is paucity of literature regarding this novel technique from the Indian subcontinent. AIMS AND OBJECTIVES: We hereby report the dosimetry, response and outcome of our small cohort of early stage non-small cell lung cancer patients treated with SBRT. MATERIALS AND METHODS: Between December 2007 and December 2010, 8 patients of early stage (T1-2N0M0) underwent SBRT at our centre. All the patients had undergone whole body PET-CT scan, MRI brain and pulmonary function test (PFT with DLCO). The SBRT schedules included 48 Gy in 6 fractions for peripherally located and 48 Gy in 8 fractions for centrally located tumors. Response and toxicity were assessed in 3 monthly follow up visits. RESULTS: The median duration of follow up was 18 months (range 8-44 months). The median age of the patients was 70 years (range 63-82 years) and the median tumor diameter was 4 cm (range 2.8-5.0 cm). The mean PTV volume was 165 cc(range 127.3- 193.9 cc). The mean dose to the PTV was 99.5% (range 97.7- 102.1%). After 3 months, 7 patients had complete metabolic response and 1 patient had partial metabolic response. Overall survival at 1.5 years was 87.5%. One patient had grade 2 pneumonitis. No toxicities of grade 3 or higher were identified. CONCLUSION: SBRT for early stage NSCLC resulted in excellent local control with minimal toxicity and can be considered as a treatment option in properly selected patients.

Comparison study of clinicoradiological profile of primary lung cancer cases: An Eastern India experience.

Context: According to the first population-based cancer registry from eastern part of India, Kolkata and its surrounding areas have the highest prevalence of lung cancer in India. However, there is very limited data from this part of the country. Aims: The aim of this study is to find out the demographic and clinicoradiological profile of primary bronchogenic carcinoma. Settings and Design: This is a retrospective review of lung cancer cases diagnosed in two tertiary institutes of Kolkata over a period of 4 years. Materials and Methods: We have reviewed the cases with proven histological or cytological diagnosis of primary bronchogenic carcinoma and chi-square test is done to calculate statistical significance. Results: Out of 607 patients, male 489 and female 118, 67.7% are from rural area, 67.2% are smoker and only 9.4% are ≤40 years of age. Smoking is the major risk factor for primary lung cancer (P = 0.000) but no significance could be established with the different histological subtypes (P = 0.207). Though squamous cell carcinoma (SCC) is the most predominant variety (35.1%), adenocarcinoma and undifferentiated type are overrepresented in ≤40 years. SCC occurs at a significantly higher age group (60.84 ± 12.16 years) than other subtypes (P = 0.000). At least 55.2% cases of nonsmall cell lung cancer and 54% of small cell lung cancer presented in very advanced stage. Conclusions: SCC is the most common histological subtype of primary bronchogenic carcinoma. The relatively increased frequency of adenocarcinoma in our study as compared to other studies from India is probably due to higher proportion of nonsmokers.

Isolated tubercular splenic abscess: Can we defer splenectomy? Our single experience with anti-tuberculous therapy alone.

Isolated splenic tuberculosis is an exceedingly rare clinical condition. Microbiological confirmation of diagnosis in such cases is quite difficult. We encountered the case of a 35-year-old female, who presented with persistent low-grade fever and weight loss. The CT scan of the abdomen revealed multiple hypodense splenic lesions. No primary focus of infection was detected in any other organs. Fine needle aspiration of splenic lesion revealed acid-fast bacilli on Ziehl-Neelsen stain. With anti-tuberculous therapy, the lesions regressed significantly in size. We stress that splenic tuberculosis should be considered as a diagnostic possibility even in immunocompetent individuals and choose combination antituberculous therapy as the first line treatment with consideration of splenectomy depending on response.

Pulmonary disease due to mycobacterium massiliense.

We report a case of a patient suffering from multidrug-resistant pulmonary tuberculosis (MDR-PTB) who later developed an invasive infection of the respiratory tract with a rapidly growing non-tuberculous mycobacteria (NTM), recently identified as Mycobacterium massiliense, closely related to M. abscessus. To the best of our knowledge, this is the first case of M. massiliense infection being reported from India.

Metastatic pleural effusion: A rare presentation of salivary gland adenoid cystic carcinoma.

Adenoid cystic carcinoma, an uncommon malignant salivary gland neoplasm, is known for its long clinical course, indolent growth, local recurrence and late distant metastasis. We report an unusual case of adenoid cystic carcinoma of the palate in a 64-year-old woman, undiagnosed for more than 15 years, who presented as malignant pleural effusion.

Correlation of Heart Rate Variability and 24- hour Mean Heart Rate with TIMI Risk Score in Acute ST-Segment Elevation Myocardial Infarction.

Background: Thrombolysis In Myocardial Infarction (TIMI) risk score, heart rate variability (HRV) and 24hour mean heart rate all are important predictor of prognosis after ST segment elevation myocardial infarction(STEMI). Correlation among these factors has not been studied thoroughly. Methods: This study was conducted in NICVD (National Institute of Cardiovascular Diseases), Dhaka, from July 2008 to June 2009. Total 105 STEMI patients were included in the study. TIMI risk score were calculated and each patient under went 24hour Holter monitoring. SDNN for HRV and mean RR interval for mean heart rate were recorded. Results : Ninety one patients (mean age 53.9 ± 10.8 years), 86.7% were males and 14( mean age 59.8 ± 8.8 years), 13.3% were female. Stratification of subjects by TIMI risk score shows that nearly 60% had risk score in the range of 3 – 7, 17. % between 0 – 2 and 24% 8 or more than 8.SDNN and RR interval stratified by TIMI risk score demonstrates that both the variables decreases significantly with the increase of TIMI risk score. Among the TIMI risk groups SDNN values were 120.0 ± 19, 871.0 ± 20.5 and 40.9 ± 6.4 msec in mild, moderate and high risk group respectively(p=<0.001). Mean RR were 836.8 ± 121.0, 776.7 ± 130.3 and 649.7 ± 75.5 msec in low, intermediate and high risk group respectively(p<0.001). There was a significant correlation between depressed SDNN and high TIMI risk score (r=.893, p=.001). High TIMI risk score also showed a negative correlation with mean RR interval (r=-574, p<0.001). Mean RR and SDNN show a perfect linear relationship (r = 0.657, p < 0.001). Conclusion: It was observed that depressed heart rate variability and increased 24-hours mean heart rate correlates with high TIMI risk score after acute ST-elevation myocardial infarction.

Mediastinal hydatid disease: An unusual presentation.

Hydatid disease is a significant health problem in endemic areas. While occurrence of the cysts in the liver and lung is common, mediastinal localisation is extremely rare. We report the case of a 35-year-old male who presented with a painless swelling on the right side of the neck and features of superior vena caval obstruction. Chest radiography and computed tomography (CT) suggested a cyst in the right upper lobe, extending into the right supraclavicular region as well as another cyst in the left lung. Thoracotomy revealed that the right-sided cyst was actually mediastinal in location and had herniated through the thoracic inlet compressing the superior vena cava (SVC). Both cysts were removed in two separate operations and symptoms of SVC compression subsided after removal of the right-sided cyst. Histopathology was consistent with a hydatid disease.

Isolation, molecular characterization and growth-promotion activities of a cold tolerant bacterium Pseudomonas sp. NARs9 (MTCC9002) from the Indian Himalayas

A bacterium that grows and expresses plant growth promotion traits at 4°C was isolated from the rhizospheric soil of Amaranth, cultivated at a high altitude location in the North Western Indian Himalayas. The isolate was Gram negative and the cells appeared as rods (2.91 x 0.71 μm in size). It grew at temperatures ranging from 4 to 30°C, with a growth optimum at 28°C. It exhibited tolerance to a wide pH range (5-10; optimum 8.0) and salt concentrations up to 6 percent (wt/vol). Although it was sensitive to Rifampicin (R 20 μg mi-1), Gentamicin (G 3 μg mi-1), and Streptomycin (S 5 μg mi-1), it showed resistance to higher concentrations of Ampicillin (A 500 μg mi-1), Penicillin (P 300 μg mi-1), Polymixin B sulphate (Pb 100 μg mi-1) and Chloramphenicol (C 200 μg mi-1). The 16S rRNA sequence analysis revealed maximum identity with Pseudomonas lurida. The bacterium produced indole Acetic Acid (IAA) and solubilizes phosphate at 4, 15 and 28°C. It also retained its ability to produce rhamnolipids and siderophores at 15°C. Seed bacterization with the isolate enhanced the germination, shoot and root lengths of thirty-day-old wheat seedlings by 19.2, 30.0 & 22.9 percent respectively, as compared to the un-inoculated controls.

Percutaneous treatment of bifurcation coronary stenosis: a long-term follow-up.

BACKGROUND: The treatment of bifurcation coronary stenosis involved several techniques in the last few years, with the use of one stent, two stents, kissing balloon, crush stenting. Basic objective was to reduce MACE rate and improve event-free survival. OBJECTIVE: To examine the performance of some techniques of stent placement adopted in the last few years by evaluating MACE (major adverse cardiac events) and TLR (target lesion revascularization). METHODS: Between 1999 and 2003, 74 consecutive patients with bifurcation lesions were treated with either stenting two vessels (type A, n = 8) or single vessels (type B, n = 66) and were followed for 30 days, 6 months, with a mean follow-up of 23 months for clinically driven MACE and TLR. RESULTS, The mean reference diameters of the main and side branches were 2.97 +/- 0.27 mm and 2.28 +/- 0.49 mm, respectively. The side branch was stented in 11% cases. Less than 30% residual stenosis in the main branch was achieved in 100% cases, <50% in the side branch in 94.5% of the cases. In-hospital major adverse cardiac events were non-Q-wave MI in 5% patients. During follow-up, death was 1.35%, subacute stent thrombosis (SAT) was 4%, and TLR (CABG) was 10.8%. Multivariate analysis showed type 1 lesion, and STEMI was associated with more MACE than others. There was 4.35-fold greater odds of MACE, associated with stenting both vessels in bifurcation lesion. CONCLUSION, Stenting of the main branch along with kissing balloon dilatation or provisional stenting of the side branch is a safe and effective treatment of coronary bifurcation lesions with acceptable TLR rates.

Adult hepatoblastoma in a female Down's.

Hepatoblastoma is most common primary malignant hepatic neoplasm in children. Median age at diagnosis is one year and mostly present by three years. This is a rare case report of a seventeen years female with Down's Syndrome presented with hepatomegaly diagnosed as hepatoblastoma.

A young male with paraplegia, massive cervical adenopathy and nondiagnostic biopsy specimens.

An 18-year-old man presenting with paraplegia due to spinal epidural infiltration at D6-D7 underwent laminectomy and spinal decompression followed by near-complete resolution of neurological symptoms; but this resolution was followed by progressively enlarging cervical lymph nodes. Leucocytosis, an elevated erythrocyte sedimentation rate, a marked polyclonal hypergammaglobulinemia and a moderate hepatosplenomegaly were found. The diagnosis of sinus histiocytosis with massive lymphadenopathy (SHML), also known as Rosai-Dorfman disease was established histologically by lymph node biopsy about 2 years after presentation.

Pyrexia of unknown origin with neutropenia, cervical lymphadenopathy, pneumonia and marrow hypoplasia.

A 56 years adult male presented with fever for 3 weeks with neutropenia and cervical lymphadenopathy with left sided pneumonitis. Histopathology of lymphnode was consistent with Kikuchi's Necrotizing Lymphadenitis. Kikuchi's disease is usually a self- limiting illness characterized by pyrexia, neutropenia and cervical lymphadenopathy in young women of Asian decent. This often leads to the misdiagnosis of lymphoma or tuberculosis. The notable feature here is an older male presented with severe neutropenia and pneumonia with hypoplastic marrow.

Unusual perforating foreign body in the neck.

Penetrating injury in the neck is not an uncommon condition, but a perforating foreign body like bamboo in the neck is uncommon. A 36 years old young man was admitted in Otolaryngology and Head Neck surgery department, Mymensingh Medical College hospital, with a history of accidental perforating injury in the neck with a bamboo, while driving a vehicle (tempo). Clinical examination revealed a bamboo measuring 4.6 X 0.09 ft. perforated in his neck from left to right. Surprisingly great vessels and air way spared. Due to difficult intubation, elective tracheostomy was done. Neck was explored and foreign body removed under general anesthesia. Haemostasis ensured and wound closed in layers after putting drain tubes. Recovery was uneventful and was discharged after three weeks.
