In vitro Impact Assessment of Aqueous Extract of Sida cordifolia Linn. Upon Rat Spermatozoa Parameters | Chapter 07 | Emerging Research in Medical Sciences Vol. 1

Sida cordifolia Linn. finds frequent mention in Ayurvedic System of Medicine for many therapeutic properties including beneficial effect upon male reproductive processes. Aim of present in vitro study was to evaluate impact of aqueous extract of Sida cordifolia roots on rat spermatozoa in terms of count, motility & morphology and through HOS study following standard assessment methods to assess any likely reproductive toxicity, spermicidal action, lethality or abnormalities in animal experimentation. Sexually mature (18-22 weeks old) male Wister rats weighing 180 to 260 gm were used. Sperms were collected from cauda epididymis of rat testes and sperm suspension was prepared by mixing them with 2 ml of 5% Sucrose at 37°C, dividing into 4 samples – control (A) and 3 drug treated samples (B, C & D) containing 10, 20 or 30 mg/ml of aqueous extract of Sida cordifolia. The various sperm parameters were observed under Olympus CX41 microscope. Sperm concentration, Progressive and Non-Progressive motility were calculated using the Neubauer Chamber. The viability and morphology of sperm suspensions were assessed using Eosin Y and Nigrosin staining method using 400 X magnification under Phase contrast microscope. Hypo-osmotic swelling (HOS) test was used to evaluate the functional integrity of plasma membrane. Treatment with aqueous extract of Sida cordifolia resulted in no significant adverse impact upon sperm count up to 30 mg/ml dose, suggesting no noticeable spermicidal effect. Progressive motility increased marginally due to intervention of Sida cordifolia in a concentration-dependent manner from 40.00±1.07 in Sample A to 43.50± 2.05 in Sample D. Similarly, percentage of normal sperms and their viability exhibited steady enhancements with increasing concentrations of research drug. The HOS test indicated no adverse structural changes in plasma membrane integrity of sperms up to 30mg/ml level. Thus, in vitro assessment of sperm motility, morphology and viability due to treatment with Sida cordifolia aqueous extract indicated no spermicidal or toxic effect and indicated small but significant enhancement in various parameters which was concentration-dependent.

Greening Regional Airports: A Vision for Carbon Neutral Infrastructure | Chapter 12 | Contemporary Perspective on Science, Technology and Research Vol. 3

 This study provides an overview of the energy demand of a regional airport, divided into individual time horizons. The electrification of aircraft systems raises the question of whether airports will be among the largest electricity consumers in our infrastructure in the future. Sustainability and especially emission reductions are significant challenges for airports that are currently being addressed. The Clean Sky 2 project GENESIS addresses the environmental sustainability of hybrid-electric 50-passenger aircraft systems in a life cycle perspective to support the development of a technology roadmap for the transition to sustainable and competitive electric aircraft systems. This article originates from the GENESIS research and describes various options for ground power supply at a regional airport. Potential solutions for airport infrastructure with a short (2030), medium (2040), and long (2050) time horizon are proposed. In addition to the environmental and conservation benefi...

Occipital Dermal Sinus Tract Causing Craniospinal Infection: A Review | Chapter 13 | New Visions in Medicine and Medical Science Vol. 4

  Dermal sinus is a rare congenital condition characterized by a pathological tract connecting the skin to deeper tissues of the central nervous system, potentially leading to severe infectious complications. It arises from a failure in the separation of ectodermal layers during early gestation. Diagnosing dermal sinus tract in newborns requires a careful physical examination, focusing on midline dimples in the occipital region associated with cutaneous abnormalities like hairy nevus or hyperpigmentation. The presence of drainage, abnormal hair distribution, or localized swelling may indicate a sinus tract. Regular examination for dimples or sinuses is recommended for infants and children with recurrent meningitis or infections. Early detection is crucial to prevent severe complications like meningitis, with Staphylococcus aureus being a common causative organism. Neuroradiological studies, including computed tomography (CT) scan and magnetic resonance imaging (MRI), with histopath...

Alkali Element Modification of Glucose Molecules as a Method to Dissolve Cancer Cells | Chapter 12 | New Visions in Medicine and Medical Science Vol. 4

  The present study highlights about alkali element modification of glucose molecules as a method to dissolve cancer cells. The central regulation of the mechanisms governing cell proliferation has little effect on cancer cells. Cancer cells are entirely independent of the central command and divide and proliferate on their own, making it challenging to activate their response mechanism. Precisely, this is the reason why they are at risk to the health of humans and/or any biological entities. Instead of trying to reconnect the central command of the growth control mechanism to cancer cells that are already out of the range, we present a method of using the cancer cell’s own irresponsive and uncontrolled growth mechanism to their disadvantage and destroy the cancer cells. We found that this is achievable in an atomic/molecular level study of the glucose molecule, which is the primary food source used for growth and energy generation by all cells in the body, including the cancer cel...
