Further Petroformynes from Both Atlantic and Mediterranean Populations of the Sponge <i>Petrosia </i><i>f</i><i>iciformis</i>

Five novel polyacetylenes (5−9) were isolated from two different populations of the sponge Petrosia ficiformis collected in the Mediterranean Sea and the Atlantic Ocean. Their structures were established by extensive NMR analysis and by comparison with known petroformynes

Phosphine-Catalyzed Aza-MBH Reactions of Vinylpyridines: Efficient and Rapid Access to 2,3,5-Triarylsubstituted 3‑Pyrrolines

Vinylpyridines have been developed in aza-Morita–Baylis–Hillman (MBH) reaction to construct triarylsubstituted 3-pyrrolines. The first electron-deficient aromatic ring is marked as an activating mode for the vinyl group in the MBH reaction. This method provides efficient and rapid access to a range of triarylpyrrolines in good yields and at an excellent level of diastereoselectivity. Moreover, the synthetic potential of this protocol is further enhanced by the straightforward synthesis of unsymmetrical tri- and polyarylsubstituted pyrroles

Association of greenspace with hypertension in adult: a systematic review and meta-analysis of epidemiological studies

Several studies have investigated the relationship of greenspace with blood pressure (BP) and hypertension, but the results were inconsistent. We aimed to assess the relationship of greenspace with BP/hypertension. We searched PubMed, Embase and Web of Science on greenspace and BP/hypertension published before 5 April 2023. The methodological quality and risk of bias were evaluated. Twenty-seven articles were included. Our results suggested that higher normalized difference vegetation index (NDVI) was associated with lower odds of hypertension and levels of SBP [for every 10% increase of NDVI 500-m and NDVI 1000-m, the ORs were 0.95 (95% CI: 0.90–0.99) and 0.95 (95% CI: 0.90–0.99), the ꞵwas -1.32 (95% CI: -2.18, -0.45) and -1.41 (95% CI: -2.57, -0.25), respectively]. This study indicated that higher exposure to greenspace might be associated with lower levels of BP and risk of hypertension. Increase green spaces should be regarded as an important public health intervention..</p
