A Rare Presentation of an Unusual Foreign Body: A Case Report.

Foreign bodies within the submandibular gland are found to be a rare phenomenon and when it occurs is most frequently found within the submandibular duct. Here, we present a case of a 33-year-old male who presented with submandibular sialadenitis caused by the foreign body penetrating the submandibular gland.

Cutaneous fungal infection in a renal transplantation patient due to a rare fungus belonging to order Pleosporales.

Fungal infections are being increasingly reported from immuno-compromised as well as immuno-competent patients. Transplant patients are on long term immunosuppressive therapy which makes them highly vulnerable to opportunistic fungal infections .These infections can be cutaneous or systemic. Several fungi have been reported to be the culprits such as Candida spp., Aspergillus spp., C. neoformans, P. carinii, and zygomycetes group of fungi. Cutaneous infections are most commonly caused by Pityriasis (tinea) versicolor, dermatophytes, and candida sp but these days the demtiaceous fungi are becoming more frequently reported .Here we report a case of post renal transplant cutaneous infection caused by dematiaceous fungus belonging to the order Pleosporales.

Isolated tear in left atrial appendage due to blunt trauma chest: a rare case report

Blunt traumatic cardiac rupture is associated with a high mortality rate. Motor vehicle accidents account for most cardiac ruptures, but crush injury is relatively rare. We describe a case of a 72-year-old man who had the left atrial appendage ruptured through blunt trauma due to a fall from scooter. Simple suture repair of the atrial appendage was achieved after clamping the base of the left atrium to control the bleeding. He recovered without complication. Traumatic injury to left atrial appendage is rarely seen and reported

Improved methods to detect GTP-binding proteins from plants.

Improved methods are described for the detection of G1P-binding proteins (G-proteins) in the protonema of moss Funaria hygrometrica and coleoptiles of corn (Zea mays) and sorghum (Sorghum vulgare). We optimized conditions for the transfer of proteins to nitrocellulose, production of high titer poly clonal anti-Gq (common) antibodies and finally the detection of G-proteins by amplification. In addition to the q-subunit of heterotrimeric G-proteins (M r 41-43 kDa), a small molecular weight class « 30 kDa) was also detected by anti-Gq (common) antibodies. An easy, reliable and efficient filter assay is also described to quantify the toxin catalyzed ADP-ribosylation. The apparent K,n of the NAD has been determined to be approximately 1.5 ~ for the microsomal fraction of moss. Inclusion of G1P stimulated ADP-ribosylation by 2-27-fold. One to three polypeptides representing the q-subunit of heterotrimeric G-proteins of (M,. 37-43 kDa) were ADP-ribosylated in all three plants. The anti-Gp (C-terminus) antibody cross-reacted strongly with 39 and 34 kDa polypeptide in moss and corn respectively. By employing improved methods two classes of G-proteins have been shown to be present in three plant species.
