acute myeloid leukemia (aml) is a type of poor prognosis hematological malignancies characterized by heterogeneous clonal expansion of myeloid progenitors. leukemic stem cells are thought to form the majority of a cell population in minimal residual diseases (mrds) which are resistant to current chemotherapeutic regimens and mediate disease relapse. current therapeutic vaccine strategies have d...

This paper shows the design and control methods of the bidirectional DC-DC converter to generate the proper DC-link voltage of a PMSM drive. Conventionally, because the controllable power of the PWM based voltage source inverter is limited by its DC-link voltage, the DC-DC converter is used for boosted DC-link voltage if the inverter source cannot generate enough operating voltage for the PMSM ...

A series of three articles present an innovative way to build advanced functionally graded materials (FGM) based on polymer/ceramic composites tailored by electrophoresis from the process principle their field grading application in power electronics. In this Part 1, is presented and relies applying a DC voltage liquid composite compound before curing order `freeze' particles where they have be...

This paper deals with a comprehensive survey on the topic of AC/DC & DC/DC converters for DC Motor Drives. A substantial number of different AC/DC and DC/DC topologies appropriate for DC motor drives are presented. This critical literature review brings out merits, demerits, and limitations besides giving the basic operating principles of various topologies. Keywords—controlled-rectifiers, chop...

The most common technique for sorting, identifying, and purifying nucleic acid fragments is agarose gel electrophoresis. performance of the electrophoresis could be impacted by buffers’ composition, ionic strength, pH characteristics [1].

Diabetes has become one of the major diseases affecting human health. Diabetic cataracts (DCs) are considered a common complication in diabetic patients. The present study investigated differences in lens proteomic profiles between DCs and age-related cataracts (ACs) to determine the mechanism underlying the formation of DCs. Intrasurgical samples were collected from eight DC patients and 12 AC...

OBJECTIVE To test the effect of some trace elements, on protein and lipoprotein glycosylation and their impact on the severity of diabetic retinopathy. METHODS A case control study was conducted in 42 diabetic patients (14 without retinopathy [DC]; 14 with non-proliferative diabetic retinopathy [NPDR]; 14 with proliferative diabetic retinopathy [PDR]) at Ebin Al-Haitham Specialized Hospital, ...

This work describes the in situ synthesis of oligonucleotide arrays on glass surfaces. These arrays are composed of features defined and separated by differential surface tension (surface tension arrays). Specifically, photolithographic methods were used to create a series of spatially addressable, circular features containing an amino-terminated organosilane coupled to the glass through a silo...

Glycosmis pentaphylla (Retz.) DC., locally known as nerapan, has long been used in Asian countries a traditional remedy for ailments attributed to microbial infections. This study aims isolate antimicrobial alkaloids from G. pentaphylla, determine their combination effects with selected agents and screen photoactivated enzymatic restriction inhibitory activity. Bioautography-guided isolation of...

in this paper, a dc-dc resonant converter with high voltage gain and small size is studied. to reduce the size and weight of this converter, the operating frequency should be as high as possible. in this research, the frequency changes from 120 to 200 khz. due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. resonant converters are su...
