Cardiac surgery is almost universally performed through a median sternotomy, an approach which is painful, unestethical, and prone to life-threatening infections. Minimally invasive cardiac surgery has tried to avoid problems associated with full sternotomy for many years. Recently, uniportal thoracic surgery was shown to be very advantageous when compared to standard thoracotomy and classical video assisted thoracic surgery (VATS). Despite very good results in lung surgery, cardiac surgery through a single thoracic port has rarely been attempted and successfully conducted...

Nearly six years since inception, uniportal video-assisted thoracic surgery (VATS) has become a growing part of major lung resections and has revolutionized the way thoracic surgeons treat pulmonary lesions. This technique is being touted for various benefits. It ensures direct visualization together with a better exposure of the lung and allows the chance of a digital palpation of the lesion through a small incision. Postoperative pain is reduced due to the involvement of only one intercostal space without rib spreading and muscle disruption...

Calcium ions (Ca(2+)) are crucial, ubiquitous, intracellular second messengers required for functional mitochondrial metabolism during uncontrolled proliferation of cancer cells. The mitochondria and the endoplasmic reticulum (ER) are connected via "mitochondria-associated ER membranes" (MAMs) where ER-mitochondria Ca(2+) transfer occurs, impacting the mitochondrial biology related to several aspects of cellular survival, autophagy, metabolism, cell death sensitivity, and metastasis, all cancer hallmarks. Cancer cells appear addicted to these constitutive ER-mitochondrial Ca(2+) fluxes for their survival, since they drive the tricarboxylic acid cycle and the production of mitochondrial substrates needed for nucleoside synthesis and proper cell cycle progression...

BACKGROUND: Simultaneous bilateral primary spontaneous pneumothorax (SBPSP) is rare, but requires surgery on both sides, in patients with definite bilateral bullae to prevent life-threatening conditions. Recently, uniportal video-assisted thoracoscopic surgery (VATS) has been widely accepted as a less invasive technique for the treatment of pneumothorax. Thus, we introduced single-staged uniportal VATS technique in the supine position, for the management of two cases of SBPSP. CASE PRESENTATION: A 17-year-old boy presented with bilateral spontaneous pneumothorax and he underwent single-staged uniportal VATS in the supine position...

Mitochondria are dynamic organelles involved in numerous physiological functions. Beyond their function in ATP production, mitochondria regulate cell death, reactive oxygen species (ROS) generation, immunity and metabolism. Mitochondria also play a key role in the buffering of cytosolic calcium, and calcium transported into the matrix regulates mitochondrial metabolism. Recently, the identification of the mitochondrial calcium uniporter (MCU) and associated regulators has allowed the characterization of new physiological roles for calcium in both mitochondrial and cellular homeostasis...

Trypanosoma cruzi is the agent of Chagas disease, and the finding that this parasite possesses a mitochondrial calcium uniporter (TcMCU) with characteristics similar to that of mammalian mitochondria was fundamental for the discovery of the molecular nature of MCU in eukaryotes. We report here that ablation of TcMCU, or its paralog TcMCUb, by clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 led to a marked decrease in mitochondrial Ca(2+) uptake without affecting the membrane potential of these cells, whereas overexpression of each gene caused a significant increase in the ability of mitochondria to accumulate Ca(2+) While TcMCU-knockout (KO) epimastigotes were viable and able to differentiate into trypomastigotes, infect host cells, and replicate normally, ablation of TcMCUb resulted in epimastigotes having an important growth defect, lower rates of respiration and metacyclogenesis, more pronounced autophagy changes under starvation, and significantly reduced infectivity...

In airway smooth muscle (ASM) cells, excitation-contraction coupling is accomplished via a cascade of events which connect an elevation of cytosolic Ca(2+) concentration ([Ca(2+)]cyt) with cross-bridge attachment and ATP-consuming mechanical work. Excitation-energy coupling is mediated by linking the elevation in [Ca(2+)]cyt to an increase in mitochondrial Ca(2+) ([Ca(2+)]mito) which in turn stimulates ATP production. Mitochondria proximity with the sarcoplasmic reticulum (SR) and plasma membrane is thought to be an important mechanism to facilitate mitochondrial Ca(2+) uptake...

Uniportal video-assisted thoracic surgery (VATS) lung wedge resection usually requires three devices, thoracoscope, lung retracting instrument and an endo-stapler cutter to perform the procedure. With advances in miniaturization of the thoracoscope and lung retracting instruments, a major limitation to operating through a smaller uniportal incision has become the endo-stapler. We describe the surgical technique for uniportal VATS laser lung resection which uses a much narrower laser catheter device to replace the endo-stapler for resection...

Uniportal video-assisted thoracic surgery (VATS) is carried out to reduce postoperative pain after treatment of thoracic diseases. Here, we report a novel method that combines a subxiphoid and intercostal uniportal VATS approach that can be used to treat bilateral pulmonary lesions simultaneously. The first case is a 50-year-old female with bilateral pulmonary lesions who received left lower lobectomy associated with right middle lobe wedge resection synchronously; the other case is a 14-year-old male who was admitted for resection of bilateral lung metastases as a result of previous osteosarcoma...

The mitochondrial calcium uniporter is a Ca(2+)-activated Ca(2+) channel complex mediating mitochondrial Ca(2+) uptake, a process crucial for Ca(2+) signaling, bioenergetics, and cell death. The uniporter is composed of the pore-forming MCU protein, the gatekeeping MICU1 and MICU2 subunits, and EMRE, a single-pass membrane protein that links MCU and MICU1 together. As a bridging subunit required for channel function, EMRE could paradoxically inhibit uniporter complex formation if expressed in excess. Here, we show that mitochondrial mAAA proteases AFG3L2 and SPG7 rapidly degrade unassembled EMRE using the energy of ATP hydrolysis...

During an inflammatory response, polarization of neutrophils is necessary for effective chemotaxis and bacterial endocytosis. Ca(2+) uptake into mitochondria through the mitochondrial calcium uniporter (MCU) is crucial for cell metabolism, signaling and survival; however, the physiological role of MCU in human neutrophils remains unclear. Here we show that MCU is vital for the polarization and chemotaxis of neutrophils. Activation of MCU by spermine promotes neutrophil polarization and chemotaxis, whereas inhibition of MCU by Ru360 blunts both processes...

Diaphragmatic plication has been a well employed method for the treatment of diaphragmatic eventration and/or paralysis. Uniportal thoracoscopic procedures seem to offer substantial benefit in terms of postoperative pain and cosmesis with similar outcomes as other surgical techniques. A 60-year-old female patient was referred to our clinic for the surgical treatment of diaphragmatic eventration of an unknown cause. The patient was referred to our institution from another hospital, where she had undergone a femoro-popliteal and crural bypass which was unsuccessful, requiring amputation of her leg...
