We report empirical evidence indicating that US net business formation has recently turned more volatile, procyclical and persistent. To study these stylized facts, we estimate a DSGE model with endogenous entry and exit. Business units feature heterogeneous productivity and they shut down if the present value of expected future dividends falls below the current liquidation value. The model provides a better fit than a constant exit rate model with the fluctuations of US business formation. The introduction of the extensive margin amplifies the effects of technology and risk-premium shocks, and reduces the procyclicality of firm-level production. The main sources of variability of the US aggregate fluctuations during the Great Recession are countercyclical technology shocks, persistent adverse risk-premium shocks, and expansionary monetary policy shocks.

Osteoarthritis (OA) is the most common chronic degenerative joint disease, characterized by cartilage damage, synovial inflammation, subchondral bone sclerosis, marginal bone loss, and osteophyte development. Clinical manifestations include inflammatory joint pain, swelling, osteophytes, and limitation of motion. The pathogenesis of osteoarthritis has not yet been fully uncovered.

Buruli ulcer (BU) is a necrotizing skin and soft tissue disease caused by Mycobacterium ulcerans that is common in hot and humid climates. Mycobacterium ulcerans is a nontuberculous mycobacterium and ubiquitous acid-fast gram-positive bacillus known to thrive in aquatic environments and water insects. The mode of transmission to humans is poorly understood and varies by geography.

The methane seeps on the Pacific margin of Costa Rica support extensive animal diversity and offer insights into deep-sea biogeography. During five expeditions between 2009 and 2019, we conducted intensive faunal sampling via 63 submersible dives to 11 localities at depths of 300-3600 m. Based on these expeditions and published literature, we compiled voucher specimens, images, and 274 newly published DNA sequences to present a taxonomic inventory of macrofaunal and megafaunal diversity with a focus on invertebrates.

Inferior vena cava (IVC) invasion by tumor thrombus poses a significant surgical challenge, often requiring vascular reconstruction. Standard methods, including prosthetic and autologous vein grafts, have limitations such as infection risks, anticoagulation demands, and increased costs. We present the case of a 66-year-old male with a right renal tumor (T3bN0M0, Neves Zincke II) and gross hematuria, who underwent radical nephrectomy with open thrombectomy.

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was designed to increase the resectable liver volume, yet it is associated with significant mortality and morbidity rates. Recently, minimally invasive techniques have been incorporated into ALPPS, with the potential to improve the procedure's safety profile whilst maintaining efficacy.
