He asserted that the job of a criminologist is not confined to the walls of the laboratory but involves the outreach and interactions with witnesses, suspects and criminals. The students received the lecture with enthusiasm as it gave a broader understanding of the actual responsibilities of a forensics expert and the different specializations within the field. The description of few cases he dealt with as an expert was received with excitement and helped to convey the inquisitiveness expected out of a forensics expert. The talk inspired students to consider Forensic Science as a career choice and laid the foundations for working towards that. The session was concluded with a vote of thanks by Ms. Jocelyn, student representative from BSc Forensic Science.

The components and working principle of this portable sequencer was explained to the students. He further explained that, this DNA sequencer is being used for a number of biological analysis techniques including de novo sequencing, targeted sequencing, RNA sequencing, met genomics, epigenetic etc. He also mentioned that, researchers from various streams like environmental research, human genetics, clinical research, microbiology, infectious diseases, cancer research, industrial diagnostics, agriculture etc. are using this portable DNA sequencer worldwide. The advantages and efficiency (a flow cell can generate 10-20 Gb of DNA sequence data) of the instrument was also discussed. He touched upon the software called “Albacore” which is used to read the sequence. Mr. Rahman, technical expert from the same company explained the mechanism of DNA sequencing and the software used to analyze sequence data.
INTERNATIONAL EXPERT LECTURE
Prof. Peter Monk on 14 September 2017, shared his research about preventing the emergence of antibiotic resistance with the students. Peter monk first explained how a bacterium develops resistance against drugs by citing simple examples and further explained the consequences of it. Peter Monk described about the receptors present on various cells in our body to which the bacteria binds. After binding to the receptors on cell surface, they grow, reproduce (forms a biofilm) and some become antibiotic resistant.
There are several ways exist to prevent bacteria from gaining antibiotic resistance, one simple way is to prevent the attachment of bacteria on target cells.
The lecture gave an insight to students and faculty about the function of tetraspanins in association with membrane protein in regulating the assembly of multimolecular signaling and new technique to prevent antimicrobial resistance “non-stick skin
INTERNATIONAL EXPERT LECTURE: Production of antibodies and using them to diagnose and cure diseases including Cancer
Dr. Lynda Patridge gave a brief introduction about antibodies and how they work against infectious organisms or cancer cell in the body on 14 September 2017. She next explained the process of generation of antibodies against certain proteins. She explained a technology that her company is working on in which certain proteins are isolated from cancer cells and antibodies are raised against those proteins.
A specific immunotoxin which can kill cancer cells will be “tagged” with that antibody and injected into the system. Since the antibodies are specific and tagged with an immunotoxin, they bind to the cancer cells and release the immunotoxin which ultimately kills the cancer cells. She called these as “Magic Bullets of Cancer.”
An interaction with Mr.Sarshad Ibnu Sayed

The lecture was an insight on bacteria that produce biofilms and the translational capabilities in the scientific arena. He made students aware of topics related to bacteriophages inhibiting Biofilms and Methicillin resistance in bacteria. Guidelines on pursuing summer fellowships and Ph.D. programs in other countries were also given during the latter part of the lecture. The session was a knowledge filled and fulfilling experience for the PG students of the Department of Life Sciences.
Dr. Robin Sebastian discussed on Effect of endosulfan on fertility
There was a visit of Dr. Robin Sebastian to our college who did an integrated Ph.D. and M.sc from IISc, Bangalore. His findings have revealed that exposure to endosulfan affects fertility in animals. He also did a molecular level study on DNA, to find out whether endosulfan modifies its structure. His interaction gave light into the topic. Thirty to 33 per cent of male mice treated with endosulfan showed clear signs of infertility. Its impact on mice is an underestimation as they used lower doses. People are exposed to much higher doses and for a longer duration. Ten animals per group were studied and the experiment was repeated three times. A dose equivalent of 3 mg/kg of body weight was used in the experiment. This dose is equivalent to that seen in places where people live. Compared with 20-700 microgram/liter serum concentration of endosulfan in humans, the treated mice had a serum concentration of just 40-60 microgram/liter.
Besides lower serum concentration, the duration of exposure was also very short. The animals were treated with four doses of endosulfan per day on every alternative day for eight days. In all, each mouse in the treatment group was exposed to 16 doses.
Detailed studies revealed that among all organs, liver, lungs and testes were maximally affected after the very first day of treatment. Kidney, liver and brain were not affected. In the testicles, many seminiferous tubules were completely devoid of mother cells that become sperms.
Since it takes 30-35 days for mother cells to become sperms, at the end of 35 days after the latest treatment, the number of sperms in treated mice was far lower compared with mice that were not treated with the pesticide (control group).
Besides lower sperm count, the motility of the sperms was affected. Twenty-five days after the last day of endosulfan treatment, the motility of sperms was significantly affected. However, at day 35, the pesticide’s effect on motility was not significant because spermatogenesis gets over by 30-35 days. So the effect probably wears off after that Unlike mice that were exposed to endosulfan for a limited period, people living in the areas where the pesticide is being used are continually exposed and may see the effect on motility continuing to be significant if an effect on humans is the same as seen in mice.
The researchers carried out mating experiments to double check the effect of lower sperm count and less motility in mice. They allowed the pesticide-treated male mice to breed with female mice (in 1:3 ratio of male and females) that were not treated with endosulfan. The mating experiments were carried during three periods (5-10 days, 20-25 days and 30-35 days after treatment with the pesticide) about 30 per cent of males did not give any progeny.
In all three mating windows, the percentage of infertile males increased as opposed to zero infertile males in control groups, indicating that the reduced sperm count and motility contributed towards reduced fertility in males,” notes the paper.
Indeed significant is that the 20-25-day window showed the most infertile males. This is only to be expected as at 25 days post-treatment, the sperm count had dropped to its lowest point and the sperms had the least motility.
Besides fertility, the pesticide was found to damage the DNA and increase the levels of error prone DNA repair leading to genomic instability. Reactive oxygen species were found to be the culprits causing damaging to DNA and the DNA repair mechanism.
