| 1 | Studies on Rhizospheric Mycoflora of Tea (Camellia sinensis): In vitro Antagonism with Dominant Bacteria显示文摘Species of Trichoderma, Penicillium, Aspergillus and Mucor were found to dominate the rhizosphere of tea bushes in different regions of the Indian Himalayas. The Himachal Himalayas were dominated by Monilia humiscola (45.08%) and Mucor hiemalis (33.11%). In the Uttaranchal Himalayas, Aspergillus clavatum dominated the rhizosphere (54.01%), followed by A. flavous (20.07%). Although the fungal isolates require a mesophillic temperature (15 ℃ to 35 ℃), the tea rhizospheric isolates tolerate a wide range of temperatures (5 ℃ to 45 ℃). When tested for pH tolerance, these fungi showed a wide range (2.0 to 13.0) of pH tolerance under in vitro conditions. Seasonal variations also influenced the colony forming units (cfu) of the rhizospheric fungi, with the maximum forming in November and March, and the minimum in December^February. During this period, the populations of the fungi were found inversely proportional to the bacterial populations. In addition, the dominant bacteria in the tea rhizosphere, i.e., Bacillus subtilis and B. mycoides, showed antagonistic activity against fungal isolates by inhibiting the growth and causing structural abnormalities in mycelium.

| 2 | Spontaneous coronary artery dissection-associated takotsubo syndrome: A systematic review of case reports显示文摘BACKGROUND Spontaneous coronary artery dissection(SCAD)is underdiagnosed and requires comprehensive angiographic findings.Few SCAD occurrences have a comparable clinical appearance as takotsubo syndrome(TTS)or exist simultaneously,making it challenging for clinicians to treat and manage.Case reports lack consolidated AIM To conduct a systematic review of available case reports on SCAD in order to investigate its potential association with TTS.METHODS SCAD-associated TTS case reports were reviewed after thoroughly screening PubMed,EMBASE,Scopus,and Google Scholar databases till January 2023.Case reports described demographics,comorbidities,imaging,management,and results.RESULTS Twelve articles about 20 female patients were analyzed.30%of patients(n=6,>60 years)were elderly(mean age 56.2±9.07 years,range 36-70 years).Canada has 9 cases,United States 3,Australia 3,Sweden 2,Japan,Denmark,and France 1.Only 5 reports identified emotional stressors in these cases while 4 reports showed physical triggers for TTS.Nine had hypertension,2 had hyperlipidemia,and 1 had prediabetes.5 patients(25%)smoked.10(50%)troponin-positive myocardial infarction patients reported chest discomfort.11(55%)of 20 instances had TTS/SCAD.12(60%)of 20 patients exhibited ST elevation and 3(15%)had T wave inversion on electrocardiogram.19/20 patients had elevated troponin.9(45%)of 20 people had apical akinesis with TTS ballooning on cardiac imaging.All 20 exhibited echocardiographic wall motion abnormalities.19(95%)of 20 coronary angiography cases had SCAD.10 of 19 SCAD patients had left anterior descending,2 diagonal,and 2 left circumflex coronary artery involvement.7 of 20 patients had left ventricular ejection fraction(LVEF)data.LVEF averaged 38.78±7.35%.5(25%)of the 20 cases underwent dual antiplatelet therapy.Three(15%)of 20 cases experienced occasional ectopic ventricular complexes,Mobitz ll AV block,and paroxysmal atrial fibrillation.All 20 cases recovered and survived.CONCLUSION Given the clinical similarities and challenges in detecting TTS and SCAD,this subset needs more research to raise awareness and reduce morbidity. | Aditi Bhanushali Muskan Kohli Ananya Prakash Svaapnika Rao Sarvepalli Anchal Pandey Olufemi Odugbemi Nafisa Reyaz Bansi Trambadia Sadhu Aishwarya Reddy Shaylika Chauhan Rupak Desai | 2023 | World Journal of Cardiology2023,15,8: | 0 |
