All the same, he was determined to amaze us. For example:Įxample No one thought that Eric could make the jump it was just too high. Bloggers, journalists, and fiction writers often use them. With that said, a fragment within a clear context can sometimes serve a useful dramatic purpose. You should always avoid sentence fragments in a formal situation and in academic writing. For instance, you could hide under their beds and wait for the dark.īoth remedies result in structurally sound sentences. If semicolons seem too formal for your purpose, you could write your text as two sentences-but remember to make sure the second one has a subject and a verb:Įxample There are many ways to frighten little brothers. Notice in the above example that by doing this, you will need to edit other parts of your fragment to make it a grammatically correct independent clause. To put it another way, you need to reinforce the fragment with a subject and verb to turn it into a sentence. Notice that to properly connect these two clauses with a semicolon, you need to do some rewriting to ensure that they both function as independent clauses. Consider the following:Įxample There are many ways to frighten little brothers for instance, you could hide under their beds and wait for the dark. Mending a sentence fragment involves one of two things: giving it the components it lacks or fastening it onto an independent clause. Fragments can sound as though they were carelessly spat out. It’s a minuscule psychological difference, but if you are corresponding in a formal setting, it’s worth taking the time and care to write a complete sentence. Adding the subject will build a more substantial, more confident-sounding sentence:Įxample I am looking forward to seeing you. Staying away from sentence fragments not only makes your writing easier to read, but it can also make you sound more refined in polite correspondence. A famous example of a short-but-complete sentence is “Jesus wept.” Nothing in the sentence needs any further explanation. I ran might be a short thought, but it has a subject (I) and a verb (ran). But this doesn’t mean that short sentences can’t be complete. In that example, creating a longer sentence was the easy solution. Here, the fragment has become a dependent clause attached to a sentence that has a subject (the wedding) and a verb (was canceled). To complete it, we need further explanation:Įxample Because of the hurricane, the wedding was canceled. It leaves us pondering what happened because of the hurricane. On its own, because of the hurricane does not form a complete thought. Here’s a glaring example of a sentence fragment: However, for a sentence to truly be complete, it must contain an independent clause, which tells the entire story even when isolated from its context. The only things a series of words needs are a capital letter at the beginning and punctuation at the end and boom! It looks like a sentence. We sometimes fail to recognize our sentence fragments because our incomplete thoughts can very easily pose as a sentence. Simply put, a sentence fragment is a clause that falls short of true sentencehood because it’s missing one out of three critical components: a subject, a verb, and a complete thought. Newman decided not to inform them that his catch was a result of pure _ he had found the error only because he had accidentally selected the wrong software to edit that day.No one escapes high school English without being penalized for writing a sentence fragment here and there, and unfortunately not everyone remembers what they are and how to fix them.

DEC-205 is an endocytic receptor that is primarily expressed in dendritic cells but also in B cells and directs captured Ag to Ag-processing compartments ( 23). This selection mechanism is further supported by studies using a DEC-205-antibody-based Ag delivery approach ( 22). Together with a mathematical simulation model ( 20), these findings support that T cells are a limiting factor and positive selection can occur in a T cell-driven selection mechanism ( 12, 21). These observations suggest that interactions between GC-B cells and TFHs are strictly controlled and therefore GC-B cells may compete for cognate T cell help. Moreover, only a limited proportion of T cells in GCs appear to actively interact with GC-B cells that are significantly more numerous than TFHs within the time window of confocal microscopic analysis ( 12, 18). Contact duration between cognate T cells and GC-B cells is shorter than that between T cell and Ag-activated B cells before GC formation ( 12, 18, 19). For promoting efficient positive selection, recycling GC-B cells reset their BCRs and MHCII before reentering the LZ ( 16, 17). Higher-affinity GC-B cells more effectively receive helper signals from TFHs because they acquire more Ag, present pMHCII at higher levels and thereby induce greater TFH activation, this is in line with studies from early B cell responses in vivo ( 14) and in vitro ( 15). LZ-B cells capture FDC-bound Ags through their BCRs, process and present them in the form of pMHCII and signals downstream of BCR-Ag engagement allow survival. In the currently favored model, positive selection occurs in an affinity-dependent manner ( 12, 13). cMyc is induced upon positive selection and its expression effectively defines positively selected GC-B cells ( 7, 8). In response to signals from BCR engagement and TFHs, a fraction of LZ-B cells are positively selected and results in evasion of apoptosis partially in a microRNA-155-dependent manner ( 10, 11). In this review, we summarize and discuss studies illustrating how positive selection of GC-B cells are triggered, what molecular and cellular events that GC-B cells undergo during the process of positive selection, and how B cell fate decisions are coordinated during positive selection.Ĭurrent Models for Affinity-Dependent Positive Selection Eventually, GC reactions produce high-affinity antibody secreting plasma cells (PCs) and memory-B cells (MBCs). GC-B cells undergo iterative rounds of mutation and selection through a migration cycle between LZ and DZ. cMyc + GC-B-cells in the LZ re-start the cell cycle and travel to the DZ for further cell division ( 7– 9). These positively selected LZ-B cells induce cMyc, a critical regulator for GC maintenance and proliferation, and cMyc positivity transiently marks “licensed” GC-B cells ( 7, 8). B cell receptor (BCR) binding of Ag by LZ-B cells results in internalization of BCR-Ag and subsequent presentation of Ag in the form of Ag-specific-peptide-major histocompatibility II (pMHCII), which enables them to receive help from T follicular helper cells (TFHs). LZ-B cells retrieve Ag on follicular dendritic cells (FDCs) that can uniquely retain and display Ag in the form of immune complex (ICs) ( 6). In the LZ, GC-B cells are selected in an Ag and T cell-dependent manner. SHM is mediated by activation-induced cytidine deaminase (AID) ( 5) and occurs in the DZ where GC-B cells extensively proliferate. GCs include two distinct regions, light zone (LZ) and dark zone (DZ) ( 4). The process of increasing antibody affinity is known as affinity maturation ( 1, 2) and results from somatic hypermutation (SHM) of immunoglobulin (Ig) genes in GC-B cells and clonal selection ( 3). This specialized microstructure transiently forms within the B cell follicles of secondary lymphoid organs during the course of T cell-dependent immune responses. Germinal centers (GCs) are sites where antibody affinity for the antigen (Ag) is improved and Ag-activated B cells differentiate, hence they are important for host defense and clearance of exogenous pathogens. However, it's crucial to reiterate, on the field, Madden genuinely feels great for the first time in a long time. In its 7.0/10 review, IGN wrote: " Madden NFL 23, though, provides a glimpse of a light at the end of the tunnel with a handful of smart enhancements to animations, AI, and passing mechanics that make subtle but meaningful improvements to the moment-to-moment football on the field… After playing Madden NFL 23 I finally have a little optimism that the series is on the right path - maybe not an emphatic 'Boom!', but clear forward progress for a series that so desperately needs it." Also giving the game a 7/10, GameSpot said: "This year's Madden is a lot like the past decade of Madden in that it suffers a number of self-inflicted wounds and returns features that were unpopular in years prior. Madden NFL 23 received "mixed or average" reviews from critics, according to Metacritic. New Field Passes come out with each major program, season, and every two weeks the Competitive Field Pass releases new rewards for players to earn. The introduction of the new Field Pass system allows players to earn up to date rewards throughout the year. Madden Ultimate Team also received several notable improvements. In July 2022, EA set up a phone line where gamers could call to complain about a player's rating being too low. The game also features player-locked touchdown camera views, additional player silhouettes body types, and improved stadium details. The PS5 and Xbox Series X/S versions of the game included new defensive animations, including mid-air collisions and tackle assists, as well as a more precise passing mechanic on offense. The franchise mode featured new additions, including free agency tools and additional trade factors. The game received mixed reviews from critics, who declared an improvement from previous games. Former head coach and broadcaster John Madden, whom the game was named after, is the cover star in honor of his death in December 2021. It marked the series debut on the Epic Games Store. Madden NFL 23 was released in August for PlayStation 4, PlayStation 5, Windows, Xbox One, and Xbox Series X/S. Based on the National Football League (NFL), it is an installment in the Madden NFL series and follows the release of Madden NFL 22. Madden NFL 23 is a 2022 American football video game developed by EA Tiburon and published by Electronic Arts. First, its antenna isn’t the highest quality, and it can limit the frequencies you’re able to pick up somewhat. There are just two details to keep in mind if you opt for this budget-friendly scanner. And it can deliver a solidly long runtime on a complete battery charge, too. It doesn’t offer much in the way of extras or frills, but it’s easy to program and the backlit LCD display allows you to easily read and see in varying levels of light or darkness. This dual-band product has a frequency range of 144 to 148 and 420 to 450 MHz, with a 128-channel memory so you can lock in your favorite channels. This police scanner is small, but it’s a convenient option if you don’t need extensive, heavy equipment and just want something simple. If you’re on a budget, you can grab the Baofeng UV-5R VHF/UHF Dual Band Radio at a great price.
