The coracoid process is a bony projection arising from the antero-lateral aspect of the scapula. The variation in the height and length of the coracoid process are responsible for altered size and shape of the space between the coracoacromial arch and the rotator cuff. The study was conducted on sixty-four dry adult human scapulae of unknown age and sex with a view to elucidate the morphological and osteometric details. The length of coracoid process on right side was 41.01±3.55 mm and it was found to be 40.88±3.83 mm on left sided. The breadth of coracoid process was observed as 13.93±1.13 mm and 13.25±1.26 mm on right and left side respectively and the difference between the two sides was statistically significant (p=0.026). Thickness of the coracoid process was 8.59±1.32 mm and 8.01±1.16 mm in right and left sided scapulae. The acromiocoracoid distance was found to be 38.48±4.03 mm on right side and 35.51±3.83 mm on left sided scapulae and the difference between to the two sides showed high statistically significance (p=0.004). Mean coracoglenoid distance was noted 26.23±3.05 mm and 24.94±2.75 mm on right and left sided scapulae respectively. Values of the thickness of coracoid process recorded in the present study are at appreciable variance with the result of previous study. The coracoid process constitutes an important component of the scapular glenoid construct and is involved in many surgical interventions on the glenohumeral joint. Comprehension of standard morphometric details of the coracoid process is vital in traumatic cases, surgical interventions and replacement surgeries in the shoulder region.

A rapid and sensitive ultra-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was developed and validated for the estimation of 17-desacetyl norgestimate in human plasma using solid-phase extraction technique. 17-desacetyl norgestimate D6 was used as the internal standard. Simple gradient chromatographic conditions and mass spectrometric detection enabled accurate and precise measurement of 17-desacetyl norgestimate at sub-picogram levels. The proposed method was validated for a linear range of 20–5000 pg/mL with a correlation coefficient Z 0.9988. The intra-run and inter-run precision and accuracy were within 10%. The overall recoveries for 17-desacetyl norgestimate and 17-desacetyl norgestimate D6 were 96.30%and 93.90%, respectively. The total run time was 4.5 min. The developed method was applied for the determination of the pharmacokinetic parameters of 17-desacetyl norgestimate following a single oral administration of a norgestimate and ethinyl estradiol 0.250 mg/0.035 mg tablets in 35 healthy female volunteers.

The existing clinical teaching in small group sessions is focused on the patient's disease. The main dual limitation is that not only does the clinical skill testing become secondary but there is also a slackening of student involvement as only 1 student is evaluated during the entire session. A new methodology of small group teaching being experimented shifted the focus to testing students' clinical skills with emphasise on team participation by daily evaluation of the entire team. The procedure involved was that the group underwent training sessions where the clinical skills were taught demonstrated and practiced on simulated patients (hear-see-do module). Later the entire small group, as a team, examined the patient and each student was evaluated for 1 of 5 specific tasks--history taking, general examination, systemic examination, discussion and case write-up. Out of 170 students, 69 students (study) and 101 students (control) were randomly chosen and trained according to the new and existing methods respectively. Senior faculty (who were blinded as to which method of teaching the student underwent) evaluated all the students. The marks obtained at 2 examinations were tabulated and compared for tests of significance using t-test. The difference in the marks obtained showed a statistically significant improvement in the study group indicating that the new module was an effective methodology of teaching. The teaching effectiveness was evaluated by student feedback regarding improvement in knowledge, clinical and communication skills and positive attitudes on a 5-point Likert scale. Psychometric analysis was very positively indicative of the success of the module.

The reconstructive surgeries utilize pes anserinus (PA) tendons, because of their lesser post-operative clinical deficits and donor site morbidity. These surgeries require anatomical knowledge about the extent of PA formation. The goal of this study was to determine the length and width of the PA formation. The objectives were to measure the distance of its upper limit, lower limit, and vertical distance from the tibial tuberosity (TT). The present descriptive cross sectional study included 53 embalmed cadaveric lower extremities. The upper and lower limits of PA were exposed with the careful dissection. Measurements of the dimensions were performed with the help of a digital vernier caliper (Mitutoyo Co., Kanagawa, Japan). The PA length, width, distance of its upper limit, lower limit, and vertical distance of it from the TT were 47.4±13.3 mm, 37.3±7.2 mm, 47.6±12.5 mm, 54.6±10.4 mm, and 39.1±14.2 mm, respectively over the right extremity. The same measurements were 46.3±14.7 mm, 39.1±9.4 mm, 39.1±5.9 mm, 49.5±8.2 mm, and 36.4±12.1 mm, respectively for the left extremity. The extent of PA was observed to be extremely variable. The preoperative knowledge about the dimensions of PA will help the plastic and orthopedic surgeon put the accurate skin incision, decreasing the donor site morbidity and biomechanical instability of the PA grafts. We suggest that, preoperative ultrasound measurement of the PA may help the operating surgeon to prevent the complications like injury to the infrapatellar branch of saphenous nerve.

BACKGROUND: The study aimed to determine if ultrasonography of masseter can be used to evaluate the outcome of transcutaneous electrical nerve stimulation (TENS) in subjects with temporomandibular disorders (TMDs) such as myositis and myofascial pain. METHODS: Fifteen TMD subjects with myofascial pain/myositis who satisfied the RDC/McNeil criteria were included in the study. All the subjects were administered TENS therapy for a period of 6 days (30 minutes per session). The mouth opening (in millimeters) and severity of pain (visual analogue scale score) and ultrasonographic thickness of the masseter (in millimeters) in the region of trigger/tender areas was assessed in all the subjects both prior and post TENS therapy. A comparison of the pre-treatment and post-treatment values of the VAS score, mouth opening and masseter thickness was done with the help of a t-test. RESULTS: There was a significant reduction in the thickness of masseter muscle (P = 0.028) and VAS scores (P < 0.001) post TENS therapy. There was also a significant improvement in the mouth opening (P = 0.011) post TENS therapy. CONCLUSIONS: In the present study, ultrasonography was found to be an effective measuring tool in the assessment of TENS therapy in subjects with myositis and myofascial pain.

The Livestock Sector of India plays an important role in livelihood security and socioeconomic development of rural households. Leptospirosis is an important zoonotic disease responsible for septicaemia, interstitial nephritis, jaundice, abortion, reproductive problem in most of the animal species. Reproductive disturbances in bovine population is most often restricted to investigation of brucellosis, however apart from brucellosis, there are many undiagnosed diseases like leptospirosis that takes a toll in the reproductive anomalies of cattle and buffalo. Hence, the present study was elucidated to screen the seroprevalence of Leptospira in cattle and buffalo in various hamlets of North India using a user friendly screening test i.e. LipL32 latex agglutination test. The overall seropositivity was found to be 26.01% (230/884) in case of bovine in this study and the LipL32 LAT showed a profound sensitivity and specificity with level of 94.97% and 99.53% respectively.

In many ways, cancer cells are different from healthy cells. A lot of tactical nano-based drug delivery systems are based on the difference between cancer and healthy cells. Currently, nanotechnology-based delivery systems are the most promising tool to deliver DNA-based products to cancer cells. This review aims to highlight the latest development in the lipids and polymeric nanocarrier for siRNA delivery to the cancer cells. It also provides the necessary information about siRNA development and its mechanism of action. Overall, this review gives us a clear picture of lipid and polymer-based drug delivery systems, which in the future could form the base to translate the basic siRNA biology into siRNA-based cancer therapies.
