Anatomy and size of , the largest belemnite.

Belemnite rostra are very abundant in Mesozoic marine deposits in many regions. Despite this abundance, soft-tissue specimens of belemnites informing about anatomy and proportions of these coleoid cephalopods are extremely rare and limited to a few moderately large genera like and . For all other genera, we can make inferences on their body proportions and body as well as mantle length by extrapolating from complete material.

Formation of 5-Aminomethyl-2,3-dihydropyridine-4(1)-ones from 4-Amino-tetrahydropyridinylidene Salts.

Various 4-aminotetrahydropyridinylidene salts were treated with aldehydes in an alkaline medium. Their conversion to 5-substituted β-hydroxyketones in a one-step reaction succeeded only with an aliphatic aldehyde. Instead, aromatic aldehydes gave 5-substituted β-aminoketones or a single δ-diketone.

Structure-Activity Relationships and Antiplasmodial Potencies of Novel 3,4-Disubstituted 1,2,5-Oxadiazoles.

The 4-substituted 3-amino-1,2,5-oxadiazole from the Malaria Box Project of the Medicines for Malaria Venture foundation shows very promising selectivity and in vitro activity against . Within the first series of new compounds, various 3-acylamino analogs were prepared. This paper now focuses on the investigation of the importance of the aromatic substituent in ring position 4.

Erector Spinae Plane Block With Liposomal Bupivacaine: Analgesic Adjunct in Adult Pectus Surgery.

Introduction: Pain management may be challenging in patients undergoing pectus excavatum (PE) bar removal surgery. To enhance recovery, opioid sparing strategies with regional anesthesia including ultrasound-guided erector spinae plane block (ESPB) have been implemented. The purpose of this study was to evaluate the safety and efficacy of bilateral ESPB with a liposomal bupivacaine/traditional bupivacaine mixture as part of an enhanced patient recovery pathway.
