Lymphoma rarely occurs during pregnancy, making this condition difficult to define. Lymphomas that occur in reproductive organs during pregnancy exhibit unique clinical characteristics. Among the limited cases, non-Hodgkin's lymphoma (NHL) shows a considerably higher incidence rate than Hodgkin's lymphoma (HL); NHL also displays clinical characteristics, such as high aggressiveness, advanced stage, and poor outcome. This study reports on four cases of lymphomas in non-gonadal organs (HL, n=2;doi:10.20892/j.issn.2095-3941.2016.0040 pmid:27807508 pmcid:PMC5069841 fatcat:m3q4zn3gzjc63liekqeaq4za4m

The two HL cases were nodular sclerosis classical HL and treated with chemotherapy after terminating the pregnancy. One of the NHL cases was primary cutaneous follicular center lymphoma, a B cell-derived indolent lymphoma. The patient was followed up without any therapy after terminating her pregnancy. The other case was a follicular lymphoma grade 3B, which was treated with chemotherapy after delivery. We also conducted a literature review of 165 lymphoma cases occurring during pregnancy reported from 1976 to 2013 to reveal the correlation between pregnancy and lymphoma progression. Immunohistochemistry studies were performed to determine the expression of estrogen/progesterone receptors (ER/PR), and ER was weakly positive and sporadic. We concluded that lymphomas occurring during pregnancy should be managed with a prompt and reasonable treatment. High estrogen level in maternal body may affect lymphoma progression.
This work aims at developing a new excitation method for thermal wave nondestructive test(NDT)-Terahertz excitation. In the paper we introduce a theoretical model of heat conduction for periodical THz excitation. BWO (backward wave oscillator) terahertz source is employed to heat a carbon fiber plate with wave absorbing coating, surface temperature variations and distributions are captured by an infrared camera, and Canny edge algorithm is used to process thermal images to show the defects.doi:10.7498/aps.61.024202 fatcat:l3bqher6xvbd3e6j3khrlc74ze

The proliferation of wireless localization technologies provides a promising future for serving human beings in indoor scenarios. Their applications include real-time tracking, activity recognition, health care, navigation, emergence detection, and target-of-interest monitoring, among others. Additionally, indoor localization technologies address the inefficiency of GPS (Global Positioning System) inside buildings. Since people spend most of their time in indoor environments, indoor trackingarXiv:1003.1833v1 fatcat:ynempxi7kzdk7kizorstacj6e4

Based on this observation, this paper aims to provide a better understanding of state-of-the-art technologies and stimulate new research efforts in this field. For these purposes, existing localization technologies that can be used for tracking individuals in indoor environments are reviewed, along with some further discussions.
We investigate stochastic optimization problems under relaxed assumptions on the distribution of noise that are motivated by empirical observations in neural network training. Standard results on optimal convergence rates for stochastic optimization assume either there exists a uniform bound on the moments of the gradient noise, or that the noise decays as the algorithm progresses. These assumptions do not match the empirical behavior of optimization algorithms used in neural network trainingarXiv:2006.04429v2 fatcat:lqhnp5nd3jcfbi4cdz5tqa4sei

We address this behavior by studying convergence rates of stochastic gradient methods subject to changing second moment (or variance) of the stochastic oracle as the iterations progress. When the variation in the noise is known, we show that it is always beneficial to adapt the step-size and exploit the noise variability. When the noise statistics are unknown, we obtain similar improvements by developing an online estimator of the noise level, thereby recovering close variants of RMSProp. Consequently, our results reveal an important scenario where adaptive stepsize methods outperform SGD.

The dinoflagellates and cyanobacteria are two major kingdoms of life producing paralytic shellfish toxins (PSTs), a large group of neurotoxic alkaloids causing paralytic shellfish poisonings around the world. In contrast to the well elucidated PST biosynthetic genes in cyanobacteria, little is known about the dinoflagellates. This study compared transcriptome profiles of a toxin-producing dinoflagellate, Alexandrium catenella (ACHK-T), and its non-toxic mutant form (ACHK-NT) using RNA-seq.

Out of them, 35 genes were found to express differentially between the two strains. The up-regulated genes in ACHK-NT were involved in photosynthesis, carbon fixation and amino acid metabolism processes, indicating that more carbon and energy were utilized for cell growth. Among the down-regulated genes, expression of a unigene assigned to the long isoform of sxtA, the initiator of toxin biosynthesis in cyanobacteria, was significantly depressed, suggesting that this long transcript of sxtA might be directly involved in toxin biosynthesis and its depression resulted in the loss of the ability to synthesize PSTs in ACHK-NT. In addition, 101 putative homologs of 12 cyanobacterial sxt genes were identified, and the sxtO and sxtZ genes were identified in dinoflagellates for the first time. The findings of this study should shed light on the biosynthesis of PSTs in the dinoflagellates.
Previous genome-wide association and validation studies suggest that LIM domain only 1 (LMO1) gene polymorphisms affect neuroblastoma susceptibility. In this work, we used Taqman methodology to genotype four LMO1 polymorphisms (rs110419 A > G, rs4758051 G > A, rs10840002 A > G and rs204938 A > G) in 118 neuroblastoma cases and 281 controls from Northern China. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the association. We found that rs4758051 G > A was associateddoi:10.18632/oncotarget.20018 pmid:29029458 pmcid:PMC5630358 fatcat:tgkjp4zvizd3na3sazuch4rtzq

Likewise, carrying the rs10840002 G allele was also associated with a decreased neuroblastoma risk in this Northern Chinese population. In a combination analysis using Southern and Northern Chinese populations, we found that those carrying the rs110419 G, rs4758051 A or rs10840002 G allele were at decreased neuroblastoma risk, and this finding was supported by a false-positive report probability analysis. These results further verify that LMO1 polymorphisms are protective against neuroblastoma. Casecontrol studies with larger samples and using other ethnicities are still needed to confirm our conclusion.

The direct linearization structure is presented of a "mild" but significant generalization of the lattice BSQ system. Some of the equations in this system were recently discovered in [J. Hietarinta, J. Phys A: Math. Theor. 44 (2011) 165204] through a search of a class of three-component systems obeying the property of multidimensional consistency. We show that all the novel equations arising in this class follow from one and the same underlying structure. Lax pairs for these systems are derivedarXiv:1112.0525v1 fatcat:c6z2tqrvdrbg7a7t5fdqienibu

With rapid urbanization occurring across developing countries since the late last century, many recent observational studies show statistically significant increases in the intensity and frequency of short-duration (i.e., less than 6 h) urban extreme rainfall (UER) events over and downwind of major megacities during the warm season, but decreasing trends in light rainfall and rainy day over surrounding areas and also in total regional rainfall [1-4] (An UER event is typically defined as adoi:10.1016/j.scib.2020.02.002 fatcat:rqrdqfgnvfhcrl2llov3b2h5kq

Moreover, the number of short-duration UER events tends to increase faster than that of long-duration ones, and the increasing UER trend appears to be more pronounced over some of China's major megacities due to more rapid urbanization during the past three decades [1-3]. As an example, a near-century climatology of hourly UER rates at a downwind maximum-accumulated rainfall station from the megacity of Shanghai is given in Fig. 1  , showing an increasing hourly rainfall trend since the rapid urbanization beginning from 1981 that is much greater than a longer-term hourly rainfall trend (Fig. 1a) . The large increases in the megacity-averaged hourly rainfall trend during Shanghai's rapid urbanization period are also evident (Fig. 1b) . In general, most UER events take place under the influences of warm and wet airstreams with weak baroclinicity, and they are highly correlated with warmer (urban-scale) surface temperatures. The UER events often cause severe urban inundation, and plague urban dwellers and sustainable development, threatening the well-beings of urban environments and society. Two recent short-duration UER events with devastating impacts in China were the record-breaking hourly rainfall rates of 85 and 184 mm h À1 occurring over the megacities of Beijing and Guangzhou on 21 July 110 105 100 95 90 85 80 75 70 32.
