Loej coast situated near Mangrol of Saurashtra region, Arabian Sea, Gujarat is supported by diverse flora and fauna. The present study aimed to document seaweed diversity and distribution along intertidal region of Loej coast by using belt transect sampling method from October 2021 to March 2022. From the study area, a total of 56 seaweed species belonging to 3 phyla, 3 classes, 16 orders, 25 families and 36 genera were recorded. Out of these 12 species were green seaweed, 14 species were brown and 30 species were red seaweed. Maximum number of species diversity was reported from class Rhodophyceae. Dictyotales (16%, species) was found to be dominant order followed by Gigartinales (14%, species); Ceramiales (11%, species). Among 25 families, Dictyotaceae was the dominant family reported with 14 species. Distribution study observed vertical distribution from the seashore side to the seaside of green, brown and red seaweed. Also, horizontal distribution of green seaweed and red seaweed were seen in the upper intertidal area and in the lower intertidal area, respectively. In species distribution behaviour, out of 56 species of seaweed; 8 species show aggregated behaviour, 10 species show the regular distribution and 38 species show random aggregation behaviour. Ulva lactuca was most abundantly and frequently found species with maximum density during the whole study period. During the present study, diversity indices like species diversity index (H') indicate healthy diverse seaweed fauna. Species richness index/Margalef's diversity index (D) was in the range of 3.37-4.81. Maximum species richness was reported in winter month February and minimum species richness in October. Pielou's evenness index (J) showed that seaweed species were unevenly distributed. [ABSTRACT FROM AUTHOR]

A single specimen of the three-spined box crab, Arcania undecimspinosa De Haan, 1841, measuring 21.0 mm CW and 20.5 mm CL, is here documented for the first time from the Arabian Sea along the north-west coast of India. Previously, the species has been only reported from the Bay of Bengal region along the Indian coast. The present study provides a detailed taxonomic description of the species with high-resolution colour photographs and line drawings, along with a key to the species of the genus Arcania known from the Indian coast.

A single male specimen of the pebble crab, Liagore rubromaculata (De Haan, 1835) measuring 40.0 × 27.0 mm (CW × CL) was observed and is recorded for the first time from the west coast of India. The species was identified by the presence of a smooth and unarmed anterolateral margin. Globally, the species has been reported from the waters of Australia, South China, Indonesia, the Persian Gulf, and the Bay of Bengal, but no report is available from the Arabian Sea. Hence the present study bestows the first confirmed record of L. rubromaculata from the Arabian Sea along the west coast of India, provided with a detailed taxonomic description of the species.

Persistent atrial standstill (PAS) is a rare disorder characterized by absence of atrial activity on the surface and intracavity electrograms, absence of atrial mechanical activity, and inability to electrically stimulate the atria. Four patients (ages 18-60 years) with PAS were evaluated. One of these (no. 3) only had right atrial (RA) standstill, whereas left atrium (LA) showed spontaneous activity and could be stimulated electrically. As RA biopsy is not possible, right ventricular (RV) endomyocardial biopsy (EMB) was obtained to identify possible atrial pathology that revealed inflammatory myocarditis, 2; amyloidosis, 1; and myocardial hypertrophy with fibrosis, 1. Three patients were given permanent pacemakers. One of these with amyloidosis died suddenly. One is lost to follow-up. The others cases are persisting with PAS. [ABSTRACT FROM AUTHOR]

Clinical and risk factor profile of 101 consecutive female patients subjected to coronary angiography was analysed. Coronary angiography showed single vessel disease (SVD) in 15.8 per cent, double vessel disease (DVD) in 12.9 per cent, triple vessel disease (TVD) in 39.6 per cent and normal coronary arteries (NC) in 30.7 per cent. Risk factor profile in patients with angiographic coronary artery disease (group II) included hypertension (HT) in 52.9 per cent, diabetes mellitus (DM) in 44.3 per cent, post menopausal state in 84.3 per cent, positive family history in 51.4 per cent, obesity in 58.3 per cent, low density and high density lipoprotein ratio (LDL/HDL) more than 3.0 in 58 per cent and smoking in 4.3 per cent. Risk factors in 31 patients with NC (group I) included HT in 29 per cent, DM in 6.5 per cent, positive family history in 45.2 per cent, obesity in 45.2 per cent, post menopausal state in 48.4 per cent, LDL/HDL ratio more than 3.0 in 30 per cent and smoking in none. The clinical presentation in group II was unstable angina in 64.3 per cent, stable angina pectoris in 24.3 per cent, myocardial infarction in 4.3 per cent and atypical chest pain in 2.8 per cent. In group I half the patients presented with atypical chest pain. The other modes of presentation included unstable angina 25.8 per cent, stable angina pectoris in 16.2 per cent and myocardial infarction in 6.5 per cent. Predictive value of exercise electrocardiography (Ex ECG) or exercise radionuclide studies (Ex RNU) was 61.7 and 68.4 per cent respectively. DM, post-menopausal state and LDL/HDL ratio more than 3 were significant risk factors in women.(ABSTRACT TRUNCATED AT 250 WORDS)

We present here a case of right-sided endomyocardial fibrosis in which there were organic changes and thrombus formation in the right atrium, its appendages and the right ventricle.
