Specialty Preference Among Medical Students and Factors Affecting It
Introduction: Medical education is one of the core part of educational system of any country. Medical education requires undergraduate students to study a wide range of medical specialties. It is often assumed that students do not make their career preferences until after they have graduated from medical school. So the reasons and factors responsible for preferences need to be found out among medical students. Material and Methods: It was a Cross sectional study on 180 medical students to assess preference for specialty and factors responsible. Results: Out of total 190 medical students more or less everyone (97.89%) wanted to pursue specialization and majority of them (96.84%) wanted to pursue the same in Medical Field(p>0.05). majority of male students were interested to pursue their specialization in the field of medicine (37.63%), surgery (23.65%) and pediatrics (13.97%). On the other hand female students were more interested in medicine (24.17%), pediatrics (32.96%) and obstetrics & gynecology (24.17%)(p<0.05). Interest, by far was found to be most common factor (76.63%) responsible for the preference of particular medical specialty among all four groups of students (1st professional-25.27%, 2nd professional-75.92%, final professional-89.47%, interns-68.42%).Conclusion: It is thus concluded there are many factors playing role in the specialty selection and preference among the medical students and should be equally justified and addressed

BiomaterialsâBased Approaches to Tumor Spheroid and Organoid Modeling
Evolving understanding of structural and biological complexity of tumors has stimulated development of physiologically relevant tumor models for cancer research and drug discovery. A major motivation for developing new tumor models is to recreate the 3D environment of tumors and contextâmediated functional regulation of cancer cells. Such models overcome many limitations of standard monolayer cancer cell cultures. Under defined culture conditions, cancer cells selfâassemble into 3D constructs known as spheroids. Additionally, cancer cells may recapitulate steps in embryonic development to selfâorganize into 3D cultures known as organoids. Importantly, spheroids and organoids reproduce morphology and biologic properties of tumors, providing valuable new tools for research, drug discovery, and precision medicine in cancer. This Progress Report discusses uses of both natural and synthetic biomaterials to culture cancer cells as spheroids or organoids, specifically highlighting studies that demonstrate how these models recapitulate key properties of native tumors. The report concludes with the perspectives on the utility of these models and areas of need for future developments to more closely mimic pathologic events in tumors.Stateâofâtheâart approaches using natural, synthetic, and composite biomaterials for 3D tumor modeling are presented in this Progress Report. Furthermore, it is discussed how these models uniquely reproduce key properties of native tumors to facilitate basic and applied cancer research and cancer drug discovery efforts.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/142941/1/adhm201700980.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/142941/2/adhm201700980-sup-0001-S1.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/142941/3/adhm201700980_am.pd
Neutron interferometric measurement of the scattering length difference between the triplet and singlet states of n-He
We report a determination of the n-He scattering length difference
(
(statistical) (systematic)) fm between the triplet and singlet
states using a neutron interferometer. This revises our previous result (-5.610 (statistical) (systematic)
fm obtained using the same technique in 2008. This revision is due to a
re-analysis of the 2008 experiment that includes a more robust treatment of the
phase shift caused by magnetic field gradients near the He cell.
Furthermore, we more than doubled our original data set from 2008 by acquiring
six months of additional data in 2013. Both the new data set and a re-analysis
of the older data are in good agreement. Scattering lengths of low Z isotopes
are valued for use in few-body nuclear effective field theories, provide
important tests of modern nuclear potential models and in the case of He
aid in the interpretation of neutron scattering from quantum liquids. The
difference was determined by measuring the relative phase
shift between two incident neutron polarizations caused by the spin-dependent
interaction with a polarized He target. The target He gas was sealed
inside a small, flat windowed glass cell that was placed in one beam path of
the interferometer. The relaxation of He polarization was monitored
continuously with neutron transmission measurements. The neutron polarization
and spin flipper efficiency were determined separately using He analyzers
and two different polarimetry analysis methods. A summary of the measured
scattering lengths for n-He with a comparison to nucleon interaction models
is given
ROLE OF EQUIPMENT MANAGEMENT IN OPTICAL TRANSPORT NETWORK
The ever-developing interest of present day society for information with enhanced execution over longer separations have made the system complex in terms of architecture, technologies, Network Elements, communication between Network Elements, security and signaling control. Equipment Management as a segment of Network Management System gives administrators the capacity to control general operation of the NEs, superintend interaction among NEs and to upper layer administration framework, thus automating the task of managing complex network. This paper presents the role of Equipment Management in Optical Transport Network and some of its challenges
Incidence of Snake Bites in Kashan, Iran During an Eight Year Period (2004-2011)
Background: Snake bites are one of the significant health problems in the tropical and subtropical regions. Snake bite is a common medical emergency in Iran, and the epidemiological features and management of such cases vary from region to region.
Objectives: This present research study was conducted to obtain new information about the epidemiology of snake bites in the region of Kashan, located in the central part of Iran.
Patients and Methods: This research was a descriptive retrospective study. Data from 2004 to 2011 of snakebite cases were collected from case reports. Information included; age and sex of the victim, district, month of incident, mortality, and time of bite.
Results: The results of this study showed that the majority of snake bite patients were male (96%). The age distribution of patients indicated that the greatest rate of snake bites occurred among the 15-24 year old group. Data collected in this study revealed that the highest incidence of snake bite cases took place in summer (60%) and the lowest number occurred in winter, with no snake bite cases being recorded. The peak number of snakebite cases was seen during June-September.
Conclusions: It was concluded that snake bite cases in Kashan are similar to other areas in Iran from an epidemiological point of view, including; age distribution rates, gender and site of the bites. The existence of Macrov ipera lebetina, a dangerous venomous snake, can cause a range of clinical effects among residents in central parts of Iran, such as Kashan area
ELECTIVE EXPERIENCES OF FOREIGN MEDICAL STUDENTS AT THE TEACHING HOSPITAL OF TRIBHUVAN UNIVERSITY INSTITUTE OF MEDICINE, NEPAL
This paper has attempted to document and analyze the trend and experiences of foreign
medical students enrolled in the elective programme organized by the Medical
Education Department (MED) at the Teaching Hospital of the Tribhuvan University
(TUTH), Institute of Medicine in Kathmandu. Elective documents have been analyzed
for the period between 1997-2000 and a written questionnaire survey has been
administered to a total of 73 foreign medical students who completed elective in the
year 2000. Over a period of four years a total of 268 students had undergone elective
posting in various departments of TUTH. More than half of the students (55%) came
from European universities. More than 60% of respondents (n=73) considered the
opportunity to see variety of patients as the main strength of the elective programme.
Overwhelming majority of respondents (95%) rated the learning experience as good
or excellent. The most favoured department was the Internal Medicine. The study
demonstrates the unique value of elective in enriching student learning in medical
education. The traditional belief that all students should have a uniform curriculum
throughout their training has been largely challenged.

The insights gained could
perhaps, inspire medical schools to seriously think about introducing elective provision
as an essential component of their undergraduate curricula.

Decoupling of a Neutron Interferometer from Temperature Gradients
Neutron interferometry enables precision measurements that are typically
operated within elaborate, multi-layered facilities which provide substantial
shielding from environmental noise. These facilities are necessary to maintain
the coherence requirements in a perfect crystal neutron interferometer which is
extremely sensitive to local environmental conditions such as temperature
gradients across the interferometer, external vibrations, and acoustic waves.
The ease of operation and breadth of applications of perfect crystal neutron
interferometry would greatly benefit from a mode of operation which relaxes
these stringent isolation requirements. Here, the INDEX Collaboration and
National Institute of Standards and Technology demonstrates the functionality
of a neutron interferometer in vacuum and characterize the use of a compact
vacuum chamber enclosure as a means to isolate the interferometer from spatial
temperature gradients and time-dependent temperature fluctuations. The vacuum
chamber is found to have no depreciable effect on the performance of the
interferometer (contrast) while improving system stability, thereby showing
that it is feasible to replace large temperature isolation and control systems
with a compact vacuum enclosure for perfect crystal neutron interferometry
