Abstract
Study question
Does the approach of sperm preparation technique plays any role in sperm DNA Integrity
Summary answer
Outcome of the semen sample is directly proportional to the choice of preparation technique. Microfluidics improves sperm selection and results in better sperm DNA integrity
What is known already
Microfluidic systems are promising tools for fluid manipulation that can noninvasively separate motile sperm with higher hydrodynamics profile from the lower ones. It also enables to manipulate micro swimmers as compared to the traditional methods that to without centrifugation .As it is already known that Semen analysis and preparation is one of the most important aspects in andrology and microfluidics can improve sperm analysis and selection, therefore increasing the ART success rates
Study design, size, duration
Comparative study from July 2019 to Dec 2021 in IVF unit of IKDRC Hospital .A total number of 900 patients were enrolled in the study and were randomized by using computer generated list then divided into two groups, Group A contains 460 samples and Group B having 440 samples.
Participants/materials, setting, methods
Group A (n = 460) sample was prepared by using Microfluidic sperm Sorting technique and Group B (n = 440) sample was prepared by conventional Swim up technique. Samples were analyzed according to WHO 2010 laboratory manual for examination and processing of human sperm, including all normozoospermic samples. Primary outcomes of the study was DNA Fragmentation index (DFI) and it was evaluated by using sperm chromatin dispersion (SCD) test and secondary outcomes was Progressive motility .
Main results and the role of chance
DNA fragmentation index is significantly lower in group A where Microfluidic Sperm Sorting technique (MFSS )is used than in group B where conventional swim up technique is use (10.06% vs 34.2%, p<0.0001) significant values implies that DNA integrity is better in group A than in group B and progressive motility was also found to be significantly higher in group A as compared to group B (57.6%vs16.9%, p <0.001).
Limitations, reasons for caution
As sample size was smaller, larger randomized control studies are needed to strengthen these results and all normal samples were used for the analysis and preparation , abnormal parameters were not involved .
Wider implications of the findings
According to our study the samples prepared by Microfluidic technique have higher DNA integrity than samples prepared by Swim up technique. Lower DNA Fragmentation index in microfluidics outcome indicates lower DNA damage. Choice of technique for the preparation of semen sample also plays a key role in better sperm selection.

Abstract
Abstract
Study question
Does semen hyper viscosity effects blastocyst formation rate
Summary answer
Hyper viscosity of semen sample later results in poor blastocyst formation rate and lower implantation rate.
What is known already
Normal range of semen hyper viscosity ranges between 12–29%.Highly viscous semen samples impairs the physical and chemical characteristics of seminal fluid and due to which seminal oxidative damage increases which further increases the ROS and reduces the sperm motility there are some factors that can affect the seminal viscosity out of which one is Male accessory gland infection, Hypo function of prostate seminal vesicles and varicoceles. SHV create hindrance in semen preparation.
Study design, size, duration
Retrospective study was conducted from June 2019 to Oct 2020 at IVF unit IKDRC hospital.
Participants/materials, setting, methods
142 patients were enrolled from June 2019 to Oct 2020 in IVF unit IKDRC hospital and divided into two groups. Group A (n = 83) patients with hyper semen viscosity and Group B (n = 69) patients with normal semen viscosity, inclusion and exclusion criteria’s were same for both the groups, only patient with normozoospermia were taken. Semen analysis was done by using WHO manual 2010.
Main results and the role of chance
In group A with hyper semen viscosity fertilization rate was (49.2% vs. 70% p = <0.001) vs in group B with normal semen viscosity which is significantly higher in group B, Blastocyst formation rate ( 18.4% vs 35% p = <0.01) and implantation rate (9.4% vs 20% p = <0.005) both are significantly higher in group B . Which implies fertilization rate , blastocyst formation rate and implantation rate is significantly lower in patients with semen hyper viscosity.
Limitations, reasons for caution
Larger randomized control studies are needed to strengthen these results.
Wider implications of the findings: Our study demonstrates that patients having higher semen viscosity have poor blastocyst formation rate and implantation rate due to oxidative stress.

Abstract
Abstract
Study question
Does sperm vitrification technique helps in increasing sperm survival and low DNA fragmentation index post warming.
Summary answer
Sperm vitrification protocol results in better motility, high progression and low DNA fragmentation index as compared to slow freezing.
What is known already
Cryopreservation is ceasing and resuming the cell metabolism, which can be achieved by different techniques like slow freezing and vitrification .Vitrification allows solidification of the cells and extracellular milieu into a glass like state without formation of ice which protects intracellular and extracellular ice formation, and further helps in avoiding different types of cryo-injuries and cellular damage. Study design, size, duration: Comparative study from July 2019 to Oct 2020 in IVF unit of IKDRC Hospital. Two hundred and ten patients were randomized by computer generated list and divided into two groups. Group 1 (n = 110) samples cryopreserved by vitrification and Group 2 (n = 100) samples cryopreserved by conventional slow freezing.
Participants/materials, setting, methods
Semen sample were analyzed by WHO 2010 laboratory manual, including all normozoospermic samples , other abnormal samples were excluded from the study . Method of semen preparation before cryopreservation is similar for both the groups, double density gradient method of preparation was used . Semen sample with high viscosity, hypo and hyper-spermia were also excluded. Similar cryovials of 2ml volume were used for both groups.
Main results and the role of chance
In group 1 where samples were cryopreserved by vitrification sperm motility was (54.3% vs 49.2%)vs in group 2 where samples were cryopreserved by slow freezing , non- significant difference were observed , but progressive motility was significantly higher in group 1 as compared to group 2 (36.8%vs17.9%) and DNA fragmentation index is significantly lower in group 1 vitrification than in group 2slow freezing ( 9.7% vs 20%).
Limitations, reasons for caution
Technical proficiency of the operator to avoid human errors and still larger randomized control studies are needed to strengthen these results
Wider implications of the findings: Our study demonstrates that vitrification is better than slow freezing of human sperm, improved survival rates with high progression were found with vitrification and low DNA fragmentation index were also observed in samples cryopreserved with vitrification protocol.

Abstract
Theileria equi and Babesia caballi are the causative agents of equine piroplasmosis (EP). Currently, imidocarb dipropionate (ID) is the only available drug for treating the clinical form of EP. Serious side effects and incomplete clearance of infection is a major drawback of ID. Heat-shock proteins (Hsp) play a vital role in the life cycle of these haemoprotozoans by preventing alteration in protein conformation. These Hsp are activated during transmission of EP sporozoites from the tick vector (poikilotherm) to the natural host (homeotherm) and facilitate parasite survival. In the present study, we targeted the heat shock protein 90 (Hsp-90) pathway of T. equi and B. caballi by using its inhibitor drug - novobiocin. Dose-dependent efficacy of novobiocin on the growth of T. equi and B. caballi was observed in in vitro culture. Additionally, we examined dose-dependent cell cytotoxicity on host peripheral mononuclear cells (PBMCs) and haemolytic activity on equine red blood cells (RBC). In vivo organ toxicity of novobiocin was also assessed in a mouse model. The IC50 (50 % inhibitory concentration) value of novobiocin against T. equi and B. caballi was 165 μM and 84.85 μM, respectively. Novobiocin significantly arrested the in vitro growth of T. equi and B. caballi parasites at 100 μM and 200 μM drug concentration, respectively. In vitro treated parasites had distorted nuclear material and showed no further viability. Based on the equine PBMCs and RBC, the drug was found to be safe even at 1000 μM concentration and the CC50 (50 % cytotoxicity concentration) values were 11.63 mM and 261.97 mM. Very high specific selective index (SSI) values (70.47 and 1587) were observed for equine PBMCs and RBC, respectively. Organ-specific biochemical markers and histopathological examination indicated no adverse effect of the drug at a dose rate of 50 mg kg body weight in the mouse model. The results demonstrate the growth inhibitory effect of novobiocin against T. equi and B. caballi parasites and its safety for host cell lines with very high SSI. Hence, it can be inferred that the Theileria/Babesia Hsp-90 family are potential drug targets worthy of further investigation.

Abstract
Extract of gum resin of B. serrata containing 60% acetyl 11-keto beta boswellic acid (AKBA) along with other constituents such as 11-keto beta-boswellic acid (KBA), acetyl beta-boswellic acid and beta-boswellic acid has been evaluated for antianaphylactic and mast cell stabilizing activity using passive paw anaphylaxis and compound 48/80 induced degranulation of mast cell methods. The extract inhibited the passive paw anaphylaxis reaction in rats in dose-dependant manner (20, 40 and 80 mg/kg, po). However, the standard dexamethasone (0.27 mg/kg, po) revealed maximum inhibition of edema as compared to the extract. A significant inhibition in the compound 48/80 induced degranulation of mast cells in dose-dependant manner (20, 40 and 80 mg/kg, po) was observed thus showing mast cell stabilizing activity. The standard disodium cromoglycate (50 mg/kg, ip) was found to demonstrate maximum per cent protection against degranulation as compared to the extract containing 60% AKBA. The results suggest promising antianaphylactic and mast cell stabilizing activity of the extract.

Abstract
We have constructed strains that allow a direct selection for mutators of Escherichia coli on a single plate medium. The plate selection is based on using two different markers whose reversion is enhanced by a given mutator. Plates containing limiting amounts of each respective nutrient allow the growth of ghost colonies or microcolonies that give rise to full-size colonies only if a reversion event occurs. Because two successive mutational events are required, mutator cells are favored to generate full-size colonies. Reversion of a third marker allows direct visualization of the mutator phenotype by the large number of blue papillae in the full-size colonies. We also describe plate selections involving three successive nutrient markers followed by a fourth papillation step. Different frameshift or base substitution mutations are used to select for mismatch-repair-defective strains (mutHLS and uvrD). We can detect and monitor mutator cells arising spontaneously, at frequencies lower than 10(-5) in the population. Also, we can measure a mutator cascade, in which one type of mutator (mutT) generates a second mutator (mutHLS) that then allows stepwise frameshift mutations. We discuss the relevance of mutators arising on a single medium as a result of cells overcoming successive growth barriers to the development and progression of cancerous tumors, some of which are mutator cell lines.
