Oncologists should measure life, not death: A newer perspective of cancer statistics
Srivastava A,Sood A
Indian Journal of Cancer , 2009,
Abstract: We discuss why we should measure parameters of ′life′ and not ′death′ in choosing a therapy for cancer and what are the flaws and difficulties in measuring cancer specific deaths. We then submit those parameters which can be measured with high precision and validity in cancer patients and so should be recorded to guide us in deciding the best therapy.
A Fast ALU Design in CMOS for Low Voltage Operation
A. Srivastava,D. Govindarajan
VLSI Design , 2002, DOI: 10.1080/10655140290011122
Abstract: A high-speed 4-bit ALU has been designed for 1 V operation to demonstrate the usefulness of the back-gate forward substrate bias (BGFSB) method in 1.2 μm N-well CMOS technology. The 4-bit ALU employs a ripple carry adder and is capable of performing eight operations - four arithmetic and four logical operations. The BGFSB voltage has been limited to |0.4| V. Delay time measurements are taken for all operations from the SPICE simulations with and without the back-gate forward substrate bias. A speed advantage of a factor of about 2–2.5 is obtained with BGFSB over the conventional design.
Application of ant colony optimization for reconfiguration of shipboard power system
SHK Vuppalapati, A Srivastava
International Journal of Engineering, Science and Technology , 2010,
Abstract: The shipboard power system (SPS) supplies energy to sophisticated systems of weapons, navigation, services and communication. Due to battle damage or faults, electric energy delivery may be interrupted to critical loads. Reconfiguration of electrical network in the SPS is necessary, to either restore the service to all the possible loads or to meet some of the operational requirements of the naval ship. In this research work, ant colony optimization (ACO) has been utilized to reconfigure given SPS network, satisfying the operational requirements, priorities of the loads and considering islanding operation and distributed generation. Graph theory has been applied to represent SPS electrical network to simplify the mathematical formulation to be used by ACO. Developed technique has been applied to an eight bus and thirteen bus representative shipboard power system model to reconfigure, while maximizing the load magnitude, or load priority, or load magnitude with priority. Satisfactory results have been obtained for both the test cases.
Autowart injection therapy for recalcitrant warts
Srivastava P,Bajaj A
Indian Journal of Dermatology , 2010,
Abstract: Background: Warts are caused by various strains of Human Papilloma Virus. They involve the epithelium of the skin and mucus membrane. Various treatment options are available, but extensive and recalcitrant warts not only cause distress to the patient cosmetically and psychologically but also pose a therapeutic challenge to the treating dermatologist. Aim: To evaluate the efficacy of autowart injection as a treatment option for extensive and recalcitrant warts. Materials and Methods: Autowart injection was prepared by removing 3 to 4 mm size wart with radiocautery which was crushed under aseptic condition and injected in the gluteal region by suspending in water for injection. Result: Results were evaluated in 53 available patients who turned up for follow-up; 35 patients (66.03%) had complete resolution in 2 months time, 12 patients (22.64%) showed partial improvement, whereas six patients (11.32%) had no improvement. Conclusion: Autowart injection is suggested as an effective and noninvasive therapeutic option in extensive and recalcitrant warts where most of the available therapies are inconvenient for both patient and treating dermatologist.

Bladder Management Outcome after Spinal Cord Injury: A Prospective Study
Srivastava A,Mathur N
Indian Journal of Physical Medicine and Rehabilitation , 2008,
Abstract: Objectives: To assess the mode of bladder management, reasons for stopping intermittent catheterization and complications encountered in bladder management Design: Prospective follow up studySetting: Dept. of PM&R of a tertiary center Methods: Spinal cord injured patients admitted in the unit with at least one-year follow up duration (Total - 479). 124 (25.9%) patients were followed up, mean duration of 23.3 months, of which 48 (38.7%) regained bladder control and were excluded. Results: At initial admission, seventy-one patients (total n=76) were discharged on clean intermittent catheterization. At follow up, 47 (66.1%) stopped intermittent catheterization; ability to pass urine was the primary reason for stopping it in 33 (63.4%) patients. Reflex emptying was the most favored mode of bladder management in 25 (32.9%) along with intermittent catheterization in 24 (31.5%) patients. Bladder autonomy and catheter free status was achieved by 54 (71%) and 39 (51.3%) patients respectively. 69 (90.7%) patients experienced urinary incontinence and 36 (34.2%) had urinary tract infection. Antibiotics and anti-cholinergics were commonly prescribed adjunctive medications in 26 (34.2%) and 16 (20.1%) patients respectively. Conclusion: Most patients stopped doing intermittent catheterization and shifted to other modes of bladder management as per their convenience due to poor follow up.
Palatal myoclonus in postinfectious opsoclonus myoclonus syndrome : a case report.
Srivastava T,Thussu A
Neurology India , 1999,
Abstract: An adult male presenting with acute onset opsoclonus, myoclonus and cerebellar ataxia is being reported. Patient had myoclonus involving limbs and palate. There are only a few reported cases associated with palatal myoclonus. Patient showed gradual spontaneous recovery. Possibility of underlying malignancy was excluded by detailed investigations.
A study of factors delaying hospital arrival of patients with acute stroke.
Srivastava A,Prasad K
Neurology India , 2001,
Abstract: Thrombolytic therapy for acute ischaemic stroke has recently become available in India but its success depends on initiating the treatment in the narrow therapeutic time window. There is commonly a delay of several hours before patients with acute stroke seek medical attention. A prospective study was conducted to assess the factors influencing this delay in admission of acute stroke cases. 110 cases (71 males, 39 females) of acute stroke that arrived within 72 hours at our hospital casualty were recruited. A standardized structured questionnaire was given to patients or their attendants. The median time to casualty arrival was 7.66 hours with 25% cases arriving within 3 hours and 49 % cases within 6 hours. Distance from hospital, contact with a local doctor and low threat perception of symptoms of stroke were independent factors associated with delay in arrival. Living in city, presence of family history and older age were associated with early arrival. There was no correlation with patients′ or attendants′ sex, educational status, history of previous stroke or transient ischaemic attack, subtype or severity of stroke, time of stroke and availability of transport. Adequate measures need to be taken to improve the public awareness of stroke and the role of local doctors.

Grain Characteristics And Cooking Quality Of Indigenous Aromatic And Non-Aromatic Genotypes Of Rice (Oryza sativa L.)
Srivastava A K
International Journal of Scientific Research and Reviews , 2013,
Abstract: Twenty four indigenous aromatic cultivars including indigenous aromatic short grain cultivars ofeastern Uttar Pradesh, basmati type varieties and five high yielding varieties of rice (Oryza sativa L.)were analyzed for their grain characteristics and physico-chemical quality attributes. The linesexhibited a great variability for all the traits studied ranging from 9.1 to 25.2g for1000 grain weight,3.33 to 8.02 mm for kernel length, 1.68 to 2.38 mm for kernel breadth, 5.25 to 14.68 mm for kernellength after cooking, 2.17 to 3.67 mm for kernel breadth after cooking, 1.68 to 6.06 for L/B ratio (aftercooking), 0.9 to 1.4 for elongation index, 1.3 to 1.9 for lengthwise elongation ratio and 1.1 to 1.6 forbreadth-wise elongation ratio. Basmati rice types exhibited excellent grain and physico-qualitycharacters. After cooking, the basmati rice showed equivalent breadth wise expansion but better lengthwise expansion that gives it a finer look and a coarser look to other types of rice. The L/b ratio furtherimproves after cooking for basmati types and short grained aromatic genotypes. The short grainaromatic lines occupied intermediate position to basmati types and non aromatic lines regardingphysical characteristics of grains like kernel length, kernel breadth and other related traits althoughthey excel in having intermediate amylose content and gelatinization temperature. These lines can befurther improved regarding their grain quality attributes by devising breeding strategies includingselection or hybridization with similar lines. These lines can serve as an alternative to the aromaticbasmati types by improving their yield level keeping their physico-chemical properties intact.
