Cell geometry and membrane protein crowding constrain Escherichia coli growth rate, overflow metabolism, respiration, and maintenance energy

FEBS Letters, EarlyView.
The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

Spatial and Temporal Dynamics of Inorganic Phosphate and Adenosine-5′-Triphosphate in the North Pacific Ocean

Frontiers in Marine Science, 2018
Temporal variability in dissolved inorganic, organic phosphate (Pi, DOP) and particulate phosphorus (PPO4) concentrations, and microbial utilization of Pi and dissolved adenosine-5′-triphosphate (DATP) was studied at Station ALOHA (22.75°N, 158°W) in the

Sistem Presensi Mahasiswa Berbasis RFID Menggunakan Raspberry Pi 1 [PDF]

Jurnal Ilmiah Teknik Elektro Komputer dan Informatika, 2016
Sistem presensi mahasiswa saat ini masih banyak dilakukan dengan penandatanganan lembar kehadiran secara manual. Hal ini tentu saja dinilai lambat dan kurang efisien, baik dari segi waktu maupun proses pengolahan datanya. Presensi manual juga dapat menimbulkan gangguan dan memecah konsentrasi mahasiswa saat melaksanakan perkuliahan.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes

FEBS Letters, EarlyView.
Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics

Early Pupil Abnormality Frequency Predicts Poor Outcomes and Enhances International Mission for Prognosis and Analysis of Clinical Trials in Traumatic Brain Injury (IMPACT) Model Prognostication in Traumatic Brain Injury

Critical Care Explorations
IMPORTANCE:. In patients with traumatic brain injury (TBI), baseline pupillary assessment is routine; however, the occurrence rate and clinical significance of pupil abnormalities over the early course of hospitalization remain poorly characterized ...

K(π, 1) arrangements

Topology, 1995
The paper is mainly devoted to the topological theory of arrangements. An \(l\)-arrangement \(A\) is a finite set of hyperplanes in \(C^ l\), and its complement \(C = C(A)\) is the open \(2l\)-manifold \(C^ l \smallsetminus \bigcup A\). If the defining linear forms have real coefficients, then \(A\) is said to be complexified, and the arrangement \(A_ ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

The $$D_{s1}(2460) \rightarrow D_s \pi ^+ \pi ^- $$ D s 1 ( 2460 ) → D s π + π - decay from a $$D_{s1}$$ D s 1 molecular perspective

European Physical Journal C: Particles and Fields
We conduct a theoretical study of the $$ D_{s1}(2460) \rightarrow D_s \pi ^+ \pi ^- $$ D s 1 ( 2460 ) → D s π + π - decay from the perspective that the $$D_{s1}$$ D s 1 is a molecular state, built mostly from the $$D^* K$$ D ∗ K and $$D_s^* \eta $$ D s ∗
